▼ Aims: This thesis aims to investigate the level of consistency in radiologists’ mammographic density (MD) reporting and to investigate the reasons that lead to reporting variability, and then to develop novel, affordable phantom images to validate imaging parameters linked with MD assessment. Methods: Project one: 17 radiologists were asked to report the BI-RADS density category and to manually segment the areas they regarded as MD for 40 clinical images. The consistency in the BI-RADS density reporting was quantified, and the impact of MD segmentation was investigated. For radiologists’ MD segmentation, the variation was quantified and the impact of image appearance was explored. Project two: A set of 100 phantom images were generated. Phantoms were manufactured using various masses and distributions of fine steel-wool set within a gelatine base to simulate the glandular and adipose tissue. A clustered lumpy background noise was added to the phantom images to simulate more complex images. The correlations between the simulated fibroglandular tissue mass and a series of imaging parameters were explored. Results: For the BI-RADS density reporting, k=0.477 for the 17 participants. In 450 out of 656 paired cases (approx. 69%), the BI-RADS categories matched the MD segmentation categories. The range of MD segmentation areas varied from 7% to 73% across the 40 images. The mean gray level value for 8 bit images being 146±19 vs. 99±14 for common and variation areas respectively. For the phantom project, very strong correlation was found for the standard deviation of mean intensity for the whole phantom image (r = 0.83, p<0.01). For the selected dense regions, very strong were shown for percentage density (r = 0.91, p<0.01), and integrated density (r = 0.93, p<0.01). Very strong and significant correlations remained after the lumpy noise was added. Conclusion: There were large variations for both MD reporting and MD identification between radiologists. In addition to subjectivity in reporting a category, the variation in radiologist MD identification is another major reason that leads to inconsistency in density reporting. Using our novel and affordable phantom, in addition to percentage density, the integrated density and the standard deviation of mean intensity may be used to facilitate MD quantification.

▼ Having a high recall rate may increase the probability of cancer being detected earlier, however it also has been related to increased false positive decisions, causing significant psychological and economical costs for both screened women and the mammography screening service. Therefore, the purpose of this thesis is to explore the impact of various recall rates on breast radiologists’ performance in a laboratory setting. Methods This study was designed to encompass two aspects 1) the effect of setting varying recall rates on the performance of breast radiologists in screening mammography 2) types of mammographic appearances of breast cancer are more likely to be missed at different recall rates. Five Australian breast radiologists were recruited to read one single test set of 200 mammographic cases (180 normal and 20 abnormal cases) over three different recall rate conditions: free recall, 15% and 10%. These radiologists were tasked with marking the location of suspicious lesions and providing a confidence. Results A significant decrease in radiologists’ performance was observed when reading at lower recall rates, with lower sensitivity (P=0.002), case location sensitivity (P=0.002) and ROC AUC (P=0.003). Reading at a lower recall rate had a significant increase in specificity (P=0.002). The second study of this thesis showed that breast radiologists demonstrated lower sensitivity and receiver ROC AUC for non-specific density (NSD) (P=0.04 and P=0.03 respectively) and mixed features (P=0.01 and P=0.04 respectively) when reading at 15% and 10% recall rates. No significant change was observed on cancer characterized with stellate masses (P=0.18 and P=0.54 respectively) and architectural distortion (P=1.00 and P=0.37 respectively). Conclusion Reducing the number of recalled cases to 10% significantly reduced breast radiologists’ performance. Stellate masses were likely to be recalled (90.0%) while NSDs were likely to be missed (45.6%) at reduced recall rates.

Masters Research - Master of Medical Science

Introduction: Between 6-10% of women attending breast screening are recalled to investigate an unclear area on the mammogram. Image quality is known to affect image interpretation and it has been suggested that the number of recalls could be reduced with improved image quality. Aim: This study aimed to investigate the effect image quality has on recall rates, to assess reader consistency using the PGMI classification system and to establish factors leading to recall. Materials and Methods: A six member panel assessed 904 sets of images (698 recalled; 206 non-recalled) through a BreastScreening Program during three separate phases (pilot, main and non-recall). The pilot study was conducted without additional training in PGMI. Levels of agreement and Kappa statistics were calculated to assess intra- and inter-consistency. The percentage of and reasons for inadequate images was calculated; while a case-control study was conducted to establish factors increasing the likelihood of a client being recalled. Results: The level of agreement between panel members significantly increased from the pilot to the main study (45.5% to 57.7%) before decreasing slightly for the non-recall (57.7% to 52.2%). Overall, 3.3% of the 904 sets of images were classed as inadequate; the most common PGMI reason was exposure (31%); the left MLO was considered the most common inadequate projection (30%), with more privately produced (66%) images considered inadequate compared to public images (34%). Inadequate image quality did not hinder the cancer detection rates. The case-control component demonstrated current and previous HRT use, increased breast density, better image quality and images being taken at a public site all contributed to a client being recalled. Conclusion: The results of this study demonstrated that inadequate image quality was not a major factor leading to recall; although twice the number of recalled images were considered inadequate compared to the non-recalled images. The use of the PGMI classification system is highly subjective, with low levels of agreement amongst users. The use of HRT, breast density, imaging site and image quality all contribute to a client being recalled.

▼ Mammography is a diagnostic imaging method in which interpretation depends on knowledge of radiological aspects as well as the clinical exam and pathophysiology of breast diseases. In this work a mammography phantom was developed to be used for training in the operation of mammographic x-ray equipment, image quality evaluation, self-examination and clinical examination of palpation. Polyurethane was used for the production of the phantoms for its physical and chemical properties and because it is one of the components normally used in prostheses. According to the range of flexibility of the polyurethane, it was possible to simulate breasts with higher or lower amount of adipose tissue. Pathologies such as areolar necrosis and tissue rejection due to surgery reconstruction after partial mastectomy were also simulated. Calcifications and nodules were simulated using the following materials: polyethylene, poly (methyl methacrylate), polyamide, polyurethane and poly (dimethyl silicone). Among these, polyethylene was able to simulate characteristics of calcification as well as breast nodules. The results from mammographic techniques used in this paper for the evaluation of the phantoms are in agreement with data found in the literature. The image analyses of four phantoms indicated significant similarities with the human skin texture and the female breast parenchyma. It was possible to detect in the radiographic images produced regions of high and low radiographic optical density, which are characteristic of breasts with regions of different amount of adipose tissue. The stiffnesses of breast phantoms were adjusted according to the formulation of the polyurethane which enabled the production of phantoms with distinct radiographic features and texture similar to human female breast parenchyma. Clinical palpation exam of the phantoms developed in this work indicated characteristics similar to human breast in skin texture, areolar region and parenchyma Advisors/Committee Members: Melo, José Daniel Diniz (advisor), CPF:46660640444 (advisor), http://lattes.cnpq.br/6572298923055649 (advisor).

▼ Background: It is generally known that mammography screening improves survival and reduces mortality from breast cancer by detecting the disease at an early stage when treatment is more effective. Despite improvements in uptakes of mammography screening, however, not all breast cancers are detected by mammograms. Some women become aware of their breast cancer through symptoms. We conducted a population-based study of the risk factors for symptomatic awareness of breast cancer among women with primary in situ or invasive breast cancer. Patients were eligible if they self-reported having had a mammogram within two years prior to either the symptom or imaging that led to the diagnosis of breast cancer. Information on patient demographics, tumor and biological characteristics, and healthcare system characteristics were collected using computer-assisted interviews. The final sample for analysis was 737 patients. Results: Among women with a recent negative mammography screen, non-Hispanic (nH) blacks and Hispanics, younger women, women with negative estrogen receptor (ER) and progesterone receptor (PR) markers, and patients with dense breasts are more likely to report symptomatic detection than nH whites, older patients, women with one or both positive ER and PR markers, and patients with fatty breasts. Tumor and biological factors (i.e., hormone receptor status and histologic grade) and breast density are strongly associated with symptomatic detection. Conclusion: Our results suggest that minorities are at risk for higher burden of disease due to late stage diagnosis (which is a consequence of the method of detection). Abnormal or suspicious mammograms in high-risk groups (e.g., being a minority, or having highly dense breasts, etc.) should warrant immediate and closer follow-up because of the likelihood of these cancers turning out to be symptomatic and consequently more advanced and aggressive. Monitoring detection patterns can serve as useful indicators of the efficacy of intervention programs designed to reduce mortality by early disease detection. Finally, although the impact was not statistically significant, improving the quality of the services available in facilities that predominantly serve minorities who come from relative disadvantage might also help alleviate the disparity.

▼ This dissertation contributes to the field of health economics, which, in the past couple of decades, has substantially increased our understanding of the determinants of human health, health-related behavior, and health care choices. A large body of literature has documented the influence of peer group behavior on individual choices. The purpose of my research is to examine the extent of such a phenomenon in breast cancer preventive behavior. Using Behavioral Risk Factors Surveillance System (BRFSS) surveys from 1993-2008, I measured the effect of other female screening behavior on an individual's decision to have a routine breast cancer screening by calculating the size of a so called social multiplier in mammography. I estimated a vector of social multipliers in the use of annual mammograms by taking the ratio of group-level effects of exogenous explanatory variables to individual-level effects of the same variables. Peer groups are defined as same-aged women living in the same geographical area: county or state. Several econometric methods were used to analyze the effect of social interactions on decision to undergo mammography, including ordinary least squares, fixed effects, the split sample instrumental variable approach, and a falsification test. My results supported the hypothesis that social interactions have an impact on the decision to have a mammogram. For all women over age 40, I found strong evidence of social interactions being associated with individual's education and ethnicity. In addition, the decision for women ages 40-49 to have a screening was subject to peer influence through their place of employment and ownership of health insurance. Finally, for women age 75 and older, being married and aging were the most important channels through which peer group influenced the decision to have a mammogram. This research has important policy implications in the presence of current health care reform that reimburses breast cancer screening at 100%, while rates of mammography receipt remain below the policy goal. Furthermore, I examined the effect of the 2009 United States Preventive Services Task Force change in screening recommendations on screening behavior. I demonstrated an immediate reduction in the receipt of mammography among women of all age groups following the revision of screening guidelines. I found that in 2010, the twelve month mammography receipt decreased by 1.97 (women ages 40-49), 2.20 (ages 50-74), and 3.61 (age 75 and older) percentage points, and the twenty-four months mammography receipt decreased by 1.47 (women ages 40-49), 1.05 (ages 50-74), and 1.92 (age 75 and older) percentage points. Analysis using a two-year follow up period after the revision of screening recommendations provided further support to this conclusion.

▼ Predictive modeling of human visual search behavior and the underlying metacognitive processes is now possible thanks to significant advances in bio-sensing device technology and machine intelligence. Eye tracking bio-sensors, for example, can measure psycho-physiological response through change events in configuration of the human eye. These events include positional changes such as visual fixation, saccadic movements, and scanpath, and non-positional changes such as blinks and pupil dilation and constriction. Using data from eye-tracking sensors, we can model human perception, cognitive processes, and responses to external stimuli. In this study, we investigated the visuo-cognitive behavior of clinicians during the diagnostic decision process for breast cancer screening under clinically equivalent experimental conditions involving multiple monitors and breast projection views. Using a head-mounted eye tracking device and a customized user interface, we recorded eye change events and diagnostic decisions from 10 clinicians (three breast-imaging radiologists and seven Radiology residents) for a corpus of 100 screening mammograms (comprising cases of varied pathology and breast parenchyma density). We proposed novel features and gaze analysis techniques, which help to encode discriminative pattern changes in positional and non-positional measures of eye events. These changes were shown to correlate with individual image readers' identity and experience level, mammographic case pathology and breast parenchyma density, and diagnostic decision. Furthermore, our results suggest that a combination of machine intelligence and bio-sensing modalities can provide adequate predictive capability for the characterization of a mammographic case and image readers diagnostic performance. Lastly, features characterizing eye movements can be utilized for biometric identification purposes. These findings are impactful in real-time performance monitoring and personalized intelligent training and evaluation systems in screening mammography. Further, the developed algorithms are applicable in other application domains involving high-risk visual tasks.

Radiologija - Radiology

UVOD: U otkrivanju i razlikovanju lezija u dojkama se primenjuje klinički pregled, radiološka dijagnostika, uglavnom mamografija i ultrasonografija i patohistološka dijagnostika. Ograničenja palpacije, mamografije i ultrazvuka i potreba da se ne previdi rani karcinom dojke, doveli su do povećanja broja biopsija, koje se najčešće izvode zbog benignih lezija. Stoga je razvijena elastografija, kao nova, komplementarna, neinvazivna tehnika, koja direktno otkriva elastične karakteristike tkiva dojke, koja se razlikuju po tvrdoći, pa invazivni karcinom ima najnižu elastičnost, a potom neinvazivni karcinom, fibrozno tkivo dojke, normalno glandularno tkivo, potom masno tkivo dojke i to ovim redom. Elastografska evaluacija se vrši kvalitativno (Tsukuba elastični skor, TES) i semikvantitativno (odnosom kompresibilnosti masti i lezije, FLR, SR). CILJ RADA: Cilj istraživanja je bio da se proceni da li elastografijom, kao novom metodom, mogu da se postignu bolji rezultati u detekciji i razlikovanju benignih i malignih lezija, u odnosu na konvencionalni ultrazvuk i mamografiju i da li kombinacija elastografije i ultrazvuka ili elastografije, ultrazvuka i mamografije može da poveća pouzdanost dijagnostike lezija u dojci. Takođe je cilj bio i da se utvrdi da li postoje neke kliničke osobine bolesnica koji mogu da utiču na ove dijagnostičke testove. MATERIJAL I METODE: Istraživanje je obavljeno u KBC „Bežanijska kosa“, u Beogradu kao jednogodišnja prospektivna studija preseka. Studija je obuhvatila ukupno 128 lezija kod 122 bolesnice (prosečne starosti 54 godine, raspona 21-84 godine) koje su dijagnostikovane kao benigne ili maligne, mamografijom i ultrazvukom i dalje analizirane elastografijom. Dijagnostički algoritam je uključivao i klinički pregled, kao prvi test. Mamografija i ultrazvuk su analizirani i kodirani po BI RADS klasifikaciji. Elastografija je određena Tsukuba elastičnim skorom (TES), sistemom od 5 kategorija i vrednošću odnosa kompresibilnosti masnog tkiva i lezije (SR, FLR). Dijagnostički rezultati su poređeni sa histopatološkim nalazom, kao standardom. Izračunati su senzitivnost, specifičnost, tačnost, pozitivna i negativna prediktivna vrednost i stepen lažno-pozitivnih i lažno-negativnih nalaza sa svaki modalitet. Primenili smo ROC analizu u proceni uloge elastografije i drugih modaliteta i njihovih kombinacija u dijagnosti lezija u dojkama...

▼ Mammography screening is effective in reducing breast cancer (BC) mortality; however there are widespread concerns that it may also lead to over-diagnosis, i.e. the detection of BC that would not have emerged clinically in a woman’s lifetime had she not participated in screening. The extent of over-diagnosis due to mammography is contested, with published estimates varying from 0% to 54%. The principal aim of this research is to quantify the level of over-diagnosis of BC associated with population-based mammography screening in South Australia (SA). The following questions are addressed: (1) Have BC incidence rates increased following the introduction of screening in SA and is the increase greater than expected based on projections of pre-screening trends?, (2) Has the prevalence of key breast cancer risk factors also increased?, (3) To what extent does hormone replacement therapy (HRT) use affect breast cancer risk and screening outcomes?, (4) Are there any differences in the underlying risk of BC among screening participants and non-participants?, and the central question (5) What is the level of over-diagnosis due to organised mammography screening in SA? Questions 2-4 relate to the potential for estimates of over-diagnosis to be confounded by risk factor differences/temporal changes. A review of previous studies of over-diagnosis due to mammography screening is included, which highlights methodological complexities relating to measurement of over-diagnosis and offers some explanations for why published estimates vary to such a great extent. The first two questions were answered through descriptive analyses of BC incidence trends in SA from 1977-2009, as well as trends in the prevalence several key breast cancer risk factors collected via the SA Health Omnibus Surveys during 1991-2009 (alcohol use, body weight, HRT use) and Australian Bureau of Statistics (fertility rates and age at first birth). The effect of HRT on various screening outcomes (e.g. screen-detection rates, interval cancer rates, recall to assessment) was examined though multivariable Poisson regression modelling using individual person level data from BreastScreen SA, which included self-reported HRT use at the time of each screening episode. Differences in underlying risk of BC between screening participants and non- participants were investigated using 2012 South Australian Health Omnibus Survey data. Two different methods were used to quantify over-diagnosis. Method 1 used a case-control design to compare screening histories for women with and without BC. Odds ratios (OR) were determined across different time intervals after screening to allow for lead time effects and applied to background reference rates based on pre-screening incidence trends. Over-diagnosis estimates were obtained by comparing cumulative incidence with and without screening. Method 2 used a lead time modelling approach in which estimates of lead time duration and screening sensitivity, and screening participation data were used to adjust the background incidence rates… Advisors/Committee Members: Roder, David Murray (advisor), Hiller, Janet Esther (advisor), Lynch, John (advisor), School of Population Health (school).

▼ Οι μικροαποτιτανώσεις είναι από τις πιο σημαντικές ενδείξεις παθήσεων του μαστού και μπορεί να αποτελέσουν πρώιμη ένδειξη καρκίνου του μαστού. Πρόκειται για εναποθέσεις ασβεστίου στο μαστό με τη διάμετρός τους να κυμαίνεται από 0.1 έως 1 mm και εμφανίζονται είτε μόνες είτε σε ομάδες. Η ακριβής τμηματοποίηση (segmentation) των μικροαποτιτανώσεων στη μαστογραφία συνεισφέρει στην εξαγωγή αξιόπιστων χαρακτηριστικών μορφολογίας, που χρησιμοποιούνται στην αυτόματη διάγνωση με υπολογιστή (Computer-aided Diagnosis, CADx). Στα πλαίσια της παρούσης διδακτορικής διατριβής προτείνεται μία νέα μέθοδος τμηματοποίησης μικροαποτιτανώσεων, η οποία αρχικά εντοπίζει σημεία του περιγράμματος αυτών. Αυτό επιτυγχάνεται με την εφαρμογή της μεθόδου ενεργών ακτίνων (Active Rays), πολικός μετασχηματισμός ενεργών περιγραμμάτων (Active Contours), σε 8 διευθύνσεις και σε δύο κλίμακες του μετασχηματισμού κυματίων (wavelet transform) με φίλτρα Β-spline. Ακολούθως, χρησιμοποιείται μέθοδος επέκτασης περιοχής (region growing) για τον ακριβή προσδιορισμό του περιγράμματος της μικροαποτιτάνωσης. Ως κριτήριο για την αύξηση της περιοχής χρησιμοποιήθηκαν τα σημεία στο περίγραμμα της μικροαποτιτάνωσης, όπως αυτά προσδιορίσθηκαν από τη μέθοδο των ενεργών ακτίνων. Επίσης, υλοποιήθηκε μέθοδος ακτινικής βάθμωσης, η οποία έχει πρόσφατα προταθεί στη βιβλιογραφία για την τμηματοποίηση μικροαποτιτανώσεων, και χρησιμοποιήθηκε για συγκριτική αξιολόγηση. Οι δύο μέθοδοι τμηματοποίησης εφαρμόστηκαν σε 149 ομάδες μικροαποτιτανώσεων, κυρίως πλειόμορφων, που αντλήθηκαν από 130 μαστογραφικές εικόνες από τη βάση DDSM (Digital Database for Screening Mammography). Η ακρίβεια τμηματοποίησης των δύο μεθόδων αξιολογήθηκε από τρεις ακτινολόγους με χρήση 5-βάθμιας κλίμακας. Η ακρίβεια τμηματοποίησης της προτεινόμενης μεθόδου βρέθηκε ίση με 3.96±0.77, 3.97±0.80 και 3.83±0.89, όπως αξιολογήθηκε από κάθε ακτινολόγο, και 2.91±0.86, 2.10±0.94 και 2.56±0.76 για την συγκρινόμενη μέθοδο. Οι διαφορές στην ακρίβεια τμηματοποίησης των δύο μεθόδων ήταν στατιστικώς σημαντικές (Wilcoxon signed-ranks test, p<0.05). Επίσης, μελετήθηκε η επίδραση των δύο μεθόδων τμηματοποίησης στην απόδοση μεθόδου αυτόματης διάγνωσης (χαρακτηρισμό) ομάδων μικροαποτιτανώσεων με υπολογιστή. Η μέθοδος αυτόματης διάγνωσης στηρίζεται σε επιβλεπόμενη ταξινόμηση προτύπων χαρακτηριστικών σχήματος ομάδας αποτιτανώσεων. Συγκεκριμένα, χρησιμοποιήθηκε ταξινομητής ελαχίστων τετραγώνων – ελάχιστης απόστασης και εξήχθησαν χαρακτηριστικά ομοιότητας και διαφοροποίησης (variability) ομάδας μικροαποτιτανώσεων, τα οποία περιγράφουν τη μορφολογία μεμονωμένων αποτιτανώσεων (εμβαδόν, μέγιστη διάμετρος, σχετική αντίθεση). Η απόδοση ταξινόμησης αποτιμήθηκε μέσω εμβαδού καμπύλης παρατηρητών (ROC). Τα χαρακτηριστικά Εμβαδού και μέγιστης Διαμέτρου επέδειξαν σημαντικά υψηλή απόδοση ταξινόμησης (Mann-Whitney U-test, p<0.05) όταν εξήχθησαν από μικροαποτιτανώσεις τμηματοποιημένες με την προτεινόμενη μέθοδο ενεργών ακτίνων (0.82±0.06 και 0.86±0.05, αντίστοιχα). Η απόδοση ταξινόμησης χαρακτηριστικών που εξήχθησαν με μέθοδο τμηματοποίησης… Advisors/Committee Members: Kωσταρίδου, Ελένη, Arikidis, Nikolaos, Κωσταρίδου, Ελένη, Παναγιωτάκης, Γεώργιος, Φωτόπουλος, Σπυρίδων, Αναστασόπουλος, Βασίλειος, Οικονόμου, Γεώργιος, Καλογεροπούλου, Χριστίνα, Σακελλαρόπουλος, Γεώργιος.

▼ Problem: Detection of breast cancer in women of low socioeconomic status, lacking health insurance, can be improved by increasing annual mammography rates, yet little is known about their screening behavior. Purpose: A retrospective subject-controlled study of an ongoing Breast Health Program, at a not-for-profit, non-government assisted, volunteer clinic, was undertaken to examine mammography usage and discovery variables. Design and Methods: English and Spanish speaking women 40 years old and over who viewed in a 7-minute breast health DVD and were offered free mammography were eligible for the study (N= 223). The Health Belief Model (HBM) (Becker, 1974) provided the study framework that utilized radiology billing records for mammography completion and a dual-language self-administered survey. Data retrieval was from March 2004 to July 2009, with DVD viewing beginning in December 2006. Recruitment occurred between July 2009 and September 2009. Results: Results revealed that 214 (96%) women had a mammography after viewing the DVD. Of the 120 subjects that had time to complete an annual mammography, 28 (23%) completed it in the 12th month, 48 (40%) completed it within 15 months, and 91 (75%) completed even if late. Only 37 subjects had time to complete a third mammography and of those only 8 completed a fourth. Significant findings found: (1) a greater proportion of women who received a reminder postcard participated in their annual mammography in the 12th month, Χ2(1) = 3.98, p = .046; (2) perceptions of breast cancer susceptibility scores were significantly lower (M = 6.89, SD = 3.18), in those who completed their annual mammography in the 12th month, t(118) = 2.03, p = .045; (3) a greater proportion of women who were knowledgeable about screening recommendations completed annual mammography, even if late, Χ2(1) = 4.736, p = .030 and; (4) Hispanic women completed at a significantly higher rate (n= 69; 81.2%) even if late, Χ2(2) = 6.450, p = .04. Implications: Longitudinal studies utilizing radiology billing records for mammography completion present real findings of mammography usage. This study's findings enhance the understanding of low-income, working uninsured women and identify new variables not found in comparative research findings.

INTRODUÇÃO: O objetivo deste estudo é determinar a correlação anatomopatológica das calcificações amorfas agrupadas diagnosticadas na mamografia digital de campo total, ou seja, das calcificações suspeitas mais tênues, uma vez que houve aumento da caracterização de calcificações na mamografia digital. MÉTODOS: Estudo retrospectivo baseado nos laudos mamográficos classificados como categoria BI-RADS 4 no primeiro ano de introdução da técnica digital, com análise dos diagnósticos anatomopatológicos das microcalcificações amorfas agrupadas submetidas à biópsia de fragmento assistida à vácuo no serviço. Calculou-se: os achados anatomopatológicos que se associaram ao achado radiológico de microcalcificações amorfas agrupadas e o valor preditivo positivo destas calcificações biopsiadas. RESULTADOS: Dos 219 achados por microcalcificações amorfas agrupadas, 78 foram submetidos à biópsia de fragmento assistida à vácuo com seguimento conhecido ou cirurgia subsequente. O diagnóstico anatomopatológico correspondeu a oito (10%) casos malignos, 36 (46%) casos benignos, e 34 (44%) diagnósticos de lesões de risco, das quais oito (10%) do subgrupo cicatriz radiada/lesões papilíferas (sete cicatrizes radiadas e um papiloma) e 26 (33%) do subgrupo atipias/ neoplasias lobulares, correspondendo a 14 (18%) hiperplasias ductais atípicas, quatro (5%) neoplasias lobulares e oito (10%) lesões de células colunares com atipia (atipia epitelial plana). A ampliação cirúrgica foi recomendada para as lesões com potencial incerto de malignidade à biópsia e realizada em 65% do subgrupo atipias/neoplasias lobulares, com taxa de subestimação nula (0/18). O tempo médio de seguimento das pacientes com diagnóstico benigno ou de lesão de risco foi 22 meses. CONCLUSÕES: Um terço das microcalcificações amorfas agrupadas em mamografia digital de campo total corresponderam a lesões precursoras representadas pelas atipias (ductais e colunares) e neoplasias lobulares. Essas lesões se associaram às calcificações amorfas agrupadas numa proporção de cerca de 3:1 em relação às lesões malignas, cujo VPP 3 foi 10

PURPOSE: To determine the anatomopathological correlation of grouped amorphous calcifications (the most tenuous of suspicious calcifications) disclosed on full-field digital mammography, given the enhanced characterization of calcifications provided by digital mammography. METHODS: A retrospective study of mammographic reports classified as BI-RADS® category 4 at a private diagnostic service specialized in breast imaging was carried out on exams performed during the first year of introducing the digital technique. The investigation entailed analysis of the anatomopathological diagnoses of BI-RADS® category 4 for grouped amorphous microcalcifications submitted to vacuum-assisted breast biopsy (VABB). Anatomopathological findings correlated to this radiological finding were determined and positive predictive value of these calcifications submitted to biopsy (PPV 3) was calculated. RESULTS: Of the 219 findings of grouped amorphous microcalcifications, 78…

OBJETIVOS: Avaliar a certeza de qualidade dos resultados mamográficos em uma instituição de referência para diagnóstico e tratamento do câncer de mama na Região Sul do Brasil, considerando as recomendações da quinta edição do BIRADS (“Breast Imaging Reporting and Data System”) para propósitos de auditoria. MATERIAL E MÉTODOS: Foi realizado um estudo de coorte observacional retrospectivo e transversal com 4911 pacientes que foram submetidas a pelo menos uma mamografia durante o ano de 2013 em um hospital público regional, ligado a uma universidade pública federal na Região Sul do Brasil. Essas pacientes foram acompanhadas até 31 de dezembro de 2014, para checar as taxas de desempenho dos resultados mamográficos na instituição em estudo, incluindo verdadeirospositivos (VP), verdadeiros-negativos (VN), falso-positivos (FP), falso-negativos (FN), valores preditivos positivos (VPP), sensibilidade e especificidade com um intervalo de confiança de 95%. RESULTADOS: O estudo demonstrou alta certeza de qualidade nos resultados das mamografias digitais diagnósticas, especialmente em relação à sensibilidade (90,21%) e especificidade (98,97%). O valor preditivo positivo (VPP) geral foi estimado em 65,3%. A taxa de interpretação anormal (ou reconvocação) foi de 12,26% e a razão de verossimilhança (“likelihood ratio”) das mamografias diagnósticas obtida foi 86,68%. CONCLUSÕES: Conclui-se que os resultados de mamografias digitais diagnósticas foram apropriados e similares aos valores pospostos pelo BIRADS. Além disso, o estudo proporcionou auto-reflexão e auto-avaliação da prática radiológica no serviço, o que é essencial para o melhoramento e processo de colaboração mais efetivo entre todos os profissionais envolvidos com o diagnóstico e tratamento do câncer de mama. Esses resultados podem incentivar outras instituições a atingirem altas taxas de qualidade de desempenho nos resultados mamográficos, apesar de possíveis limitações estruturais quando comparadas a instituições de países desenvolvidos.

Objective: Evaluation of the diagnostic value of magnetic resonance mammography and comparison with conventional mammography and ultrasonography in cases of women with suspicious breast lesions. Subjects and Methods: A hundred women (age range 34-83 years) with 111 focal breast lesions were examined with mammography, ultrasonography and dynamic magnetic resonance mammography. The lesions were classified according to the BI-RADS lexicon of the American College of Radiology for each diagnostic method. Histological reports were available after biopsy or surgical excision of the lesions. Results: Pathological examination confirmed that 73 lesions were malignant and 38 benign. Conventional mammography estimated a total of 84/111 lesions as malignant with 63 true positive lesions, ultrasonography estimated a total of 92/111 lesions as malignant with 63 true positive lesions and magnetic resonance mammography estimated a total of 83/111 lesions as malignant with 70 true positive lesions. Sensitivity and specificity of magnetic resonance mammography in the diagnosis of malignancy was 95.9% and 34.2%, of conventional mammography 81.8% and 38.2% and of ultrasonography 86.3% and 76.3%. Negative predictive value for magnetic resonance mammography was 81.2%, for ultrasonography 73.4% and for mammography 48.2% for malignancies. Conclusion: Magnetic resonance mammography has the highest negative predictive value compared with mammography and ultrasound in cases of suspicious breast lesions. The combination of morphologic and enhancement criteria can improve the diagnostic capability of MRM in breast lesion characterization.

▼ Sequential mammograms contain important information, such as changes of the breast or developments of the masses, for diagnosis of disease. Comparison of sequential mammograms plays an important part for radiologists in identifying malignant masses. However, currently computer-aided detection (CAD) programs can not use such information eciently. The diculties lie in the registration of sequential mammograms. Most of current methods register sequential mammograms based on control points and image transformations. For these methods to work, extraction and correspondence of the control points is essential. This thesis presents a new approach in registering mammograms. The proposed method registers mammograms by associating mass-like objects in sequential mammograms directly. The mass-like objects appear in the images of normal breasts as well as images of breast with cancer. When the mass-like objects in sequential mammograms are accurately associated, measurements of changes in mass-like objects over time become possible. This is an important way to distinguish mass-like objects associated with cancer from cysts or other benign objects. The proposed method is based on graph matching. It uses the internal structure of the breast represented by the spatial relation between the mass-like objects to establish a correspondence between the sequential mammograms. In this method, the mammogram is firstly segmented into separate components using an adaptive pyramid (AP) segmentation algorithm. A series of filters, based on the features of components, is then applied to the components to remove the undesired ones. The remaining components, the mass-like objects, are represented by a complete graph. The spatial relations between the remaining mass-like objects are expressed by fuzzy spatial relation representation and are associated to the edges of the graph as weights. Association of the mass-like objects of two sequential mammograms is realized by finding a common subgraph of the corresponding two graphs using the backtrack algorithm. The segmentation methods developed in the course of this work were tested on a separate problem in computer-aided detection of breast cancer, namely the automatic extraction of the pectoral muscle. The graph matching method was tested independently of the segmentation method on artificially distorted mammograms and the full process, including the segmentation and the graph matching, was evaluated on 95 temporal mammogram pairs. The present implementation indicates only a small improvement in cancer detection rates but also presents opportunities for a substantial development of the basic method in the future.

▼ The overall goal of this dissertation is to optimize and evaluate the performance of the single photon emission computed tomography (SPECT) subsystem of a dedicated three-dimensional (3D) dual-modality breast imaging system for enhanced semi-automated, quantitative clinical imaging. This novel hybrid imaging system combines functional or molecular information obtained with a SPECT subsystem with high-resolution anatomical imaging obtained with a low dose x-ray Computed Tomography (CT) subsystem. In this new breast imaging paradigm, coined "mammotomography," the subject is imaged lying prone while the individual subsystems sweep 3-dimensionally about her uncompressed, pendant breast, providing patient comfort compared to traditional compression-based imaging modalities along with high fidelity and information rich images for the clinician. System evaluation includes a direct comparison between dedicated 3D SPECT and dedicated 2D scintimammography imaging using the same high performance, semi-conductor gamma camera. Due to the greater positioning flexibility of the SPECT system gantry, under a wide range of measurement conditions, statistically significantly (p<0.05) more lesions and smaller lesion sizes were detected with dedicated breast SPECT than with compressed breast scintimammography. The importance of good energy resolution for uncompressed SPECT breast imaging was also investigated. Results clearly illustrate both visual and quantitative differences between the various energy windows, with energy windows slightly wider than the system resolution having the best image contrast and quality. An observer-based contrast-detail study was performed in an effort to evaluate the limits of object detectability under various imaging conditions. The smallest object detail was observed using a 45-degree tilted trajectory acquisition. The complex 3D projected sine wave acquisition, however, had the most consistent combined intra and inter-observer results, making it potentially the best imaging approach for consistent clinical imaging. Automatic ROR contouring is implemented using a dual-layer light curtain design, ensuring that an arbitrarily shaped breast is within ~1 cm of the camera face, but no closer than 0.5 cm at every projection angle of a scan. Autocontouring enables simplified routine scanning using complex 3D trajectories, and yields improved image quality. Absolute quantification capabilities are also integrated into the SPECT system, allowing the calculation of in vivo total lesion activity. Initial feasibility studies in controlled low noise experiments show promising results with total activity agreement within 10% of the dose calibrator values. The SPECT system is integrated with a CT scanner for added diagnostic power. Initial human subject studies demonstrate the clinical potential of the hybrid SPECT-CT breast imaging system. The reconstructed SPECT-CT images illustrate the power of fusing functional SPECT information to localize lesions not easily seen in the anatomical… Advisors/Committee Members: Tornai, Martin P (advisor).

Os critérios de qualidade de imagem mamógrafica publicados pela European Commission foram implementados em três mamógrafos de um mesmo departamento de radiologia de um hospital na cidade de São Paulo. Dentre os mamógrafos dois apresentam o sistema tela-filme e um deles apresenta o sistema digital indireto. Durante o período de coleta de dados, foi observada a necessidade de realizar um estudo sobre índice de rejeição de imagem em cada mamógrafo. Portanto, este estudo foi realizado e, em seguida, foram feitas comparações, entre os mamógrafos, do índice de rejeição de imagem e da porcentagem de imagens que atendiam a cada critério de qualidade de imagem. Paralelamente a esses estudos, foi realizado o estudo das doses na entrada da pele e glandular média. Essas doses foram estimadas, baseando-se em diferentes metodologias apresentadas por diferentes grupos de estudiosos, para todas as combinações anodo-filtro apresentadas pelo equipamento. Para estimar a dose na entrada da pele pelo método publicado no guia da ANVISA e a dose glandular média pelo método de Wu, foi desenvolvido um manequim no formato bem próximo ao de uma mama, em diferentes espessuras de PMMA. Por fim, associou-se a qualidade da imagem com a dose recebida pela paciente. O equipamento digital apresentou melhores resultados na avaliação dos critérios de qualidade, menor índice de rejeição de imagem e menores valores de dose glandular média e na entrada da pele em todos os métodos estudados. Porém não é suficiente, pois não atende às pacientes que possuem mamas grandes.

The mammographic image quality criteria published by European Commission were implemented in three mammography equipments of a same radiology department in a hospital of Sao Paulo city. Among the mammography equipments, two use the screen-film system and one of them uses the indirect digital system. During the data collection, it was noted the need to conduct a study about image rejection in each mammography equipment. Therefore, this study was realized and, after that, the results in each mammography equipment of image rejection and image percentage that present each quality criterion it were compared. At the same time of this studies, it was realized other study about surface entrance dose and average glandular dose. These doses it was estimated based on different methods published by different groups of researcher, for all combinations anodefilter available in the equipment. To estimate the surface entrance dose following the methodology published in ANVISA guide and the average glandular dose following the Wu methodology, it was developed a phantom, in different thicknesses of acrylic, to simulate a breast. Finally, the image quality it was associated with the dose received by patient. The digital equipment shows better results in the evaluation of quality criteria, lower rate of image rejection and lower values of average glandular dose and surface entrance dose in all methods studied. But it is not sufficient, because is not adequate for patients with great breast.
