RESUMO
RATIONALE AND OBJECTIVES: To assess patient preferences for breast radiologists' attire and appearance. MATERIALS AND METHODS: A multi-institutional anonymous, voluntary 19-question survey was administered to patients undergoing screening and diagnostic mammography examinations over a 5-week period. Using a 5-point Likert scale, respondents were asked about their preferences for gender-neutral attire (white coat), male-presenting attire (scrubs, dress shirt with tie, or dress shirt without tie), and female-presenting attire (scrubs, dress, blouse with pants, and blouse with skirt). Patient responses were compared to demographic data using bivariable analysis and multivariable regression. RESULTS: Response rate was 84.7% (957/1130). Mean respondent age was 57.2 years±11.9. Most respondents agreed/strongly agreed that the breast radiologist's appearance mattered (52.5%, 502/956) followed by being indifferent (28.1%, 269/956). Respondents with greater education levels felt less strongly (p=0.001) about the radiologist's appearance: 63.3% (70/110) less than college cared about appearance compared to 53.5% (266/497) college/vocational and 47.4% (165/348) graduate. Most respondents felt indifferent about a breast radiologist wearing a white coat (68.9%, 657/954) or about male-presenting breast radiologists wearing a tie (77.1%, 734/952) without significant demographic differences. Almost all respondents either prefer/strongly prefer (60.1%, 572/951) or were indifferent (39.6%, 377/951) to all breast radiologists wearing scrubs when performing procedures. While respondents approved of all attire choices overall, most respondents preferred scrubs for both male- and female-presenting breast radiologists (64.0%, 612/957 and 64.9%, 621/957, respectively). CONCLUSION: A variety of breast radiologists' attire can be worn while maintaining provider professionalism and without compromising patient expectations.

OBJECTIVE: To assess the impact of interruptions on radiologists' efficiency, accuracy, and job satisfaction in interpreting screening mammograms. METHODS: This institutional review board-approved retrospective reader study recruited nine breast radiologists from a single academic institution [name withheld] to interpret 150 screening mammograms performed between December 1, 2008, and December 31, 2015 under two different reading conditions, as follows: (1) uninterrupted batch reading and (2) interrupted reading. The 150 cases consisted of 125 normal mammograms and 25 mammograms with subtle breast cancers. Cases were divided into two groups of 75 cases each (cohort 1 and cohort 2), with a comparable distribution of cancer cases. Four rounds of 75 cases each were conducted with a 6-week washout period between rounds 2 and 3. After completing each interpretation session, readers completed a seven-question survey, assessing perceptions of mental and physical effort, level of frustration, and performance satisfaction. Clinical performance metrics (reading time, recall rate, sensitivity, specificity, accuracy, and positive predictive value 1) were calculated. RESULTS: Recall rates were significantly (P = .04) higher during interrupted reading sessions (35.4%) than they were during uninterrupted batch reading sessions (31.4%). Accuracy was significantly (P = .049) worse in the interrupted reading sessions (69.5%), compared with uninterrupted sessions (73.6%). Differences in overall image interpretation times were not statistically significant (P = .065). Compared with uninterrupted batch reading sessions, readers during interrupted sessions reported feeling busier (P < .001), encountered higher levels of cognitive demand (P = .005), experienced elevated levels of physical fatigue (P = .004), and expressed lower levels of satisfaction with their performance (P = .041). CONCLUSION: Interruptions during interpretation of screening mammography have deleterious effects on physician performance and their sense of well-being.
RESUMO
OBJECTIVE: To examine time from screening to diagnostic workup, biopsy, and surgery for non-Hispanic White (NHW) and Black women following implementation of a same-day biopsy program. METHODS: All NHW and Black women with BI-RADS category 0 screening mammogram at Duke University Hospital were identified between August 1, 2020, and August 1, 2021. Patient characteristics were recorded. Time between screening mammogram, diagnostic workup, breast biopsy, surgical consultation, and surgery were recorded. Comparisons were made between NHW and Black women using a multivariable regression model. Diagnostic imaging to biopsy time interval was compared to historical averages before same-day biopsy implementation. RESULTS: There were 2156 women: 69.9% NHW (1508/2156) and 30.1% Black (648/2156). Mean ± standard deviation time from screening to diagnostic imaging overall was 13.5â ±â 32.5 days but longer for Black (18.0â ±â 48.3 days) than for NHW women (11.5â ±â 22.2 days) (Pâ <â 0.001). The mean time from diagnostic mammogram to biopsy was 5.9â ±â 18.9 days, longer for Black (9.0â ±â 27.9 days) than for NHW women (4.4â ±â 11.8 days) (Pâ =â 0.017). The same-day biopsy program shortened the time from diagnostic imaging to biopsy overall (12.5â ±â 12.4 days vs 5.9â ±â 18.9 days; Pâ <â 0.001), with a significant reduction for NHW women (12.4â ±â 11.7 days vs 4.4â ±â 11.8 days) (Pâ <â 0.001) but not Black women (11.5â ±â 9.9 days vs 9.0â ±â 27.9 days) (Pâ =â 0.527). CONCLUSION: Disparities exist along the breast imaging pathway. A same-day biopsy program benefited NHW women more than Black women.

OBJECTIVE: Evaluate the effectiveness of alcohol sclerotherapy in postoperative breast and axillary seromas. METHODS: This was an IRB-approved retrospective review of consecutive patients from 2017 to 2021. The procedure involves aspiration of seroma fluid, injection of ethanol for 15 to 30 minutes, and then aspiration of the injected ethanol. Following review of the medical record, patient and procedure data were recorded. Success was defined as no recurrence of seroma. Statistical analysis was performed using a chi-square or t-test, as appropriate. RESULTS: Twenty seromas were treated in 19 patients (mean age, 63 years; range, 49-79) following mastectomy (9/20, 45%), lumpectomy (25%, 5/20), axillary nodal dissection (5/20, 25%), or chest wall surgery (1/20, 5%). The mean seroma volume was 146â ±â 165 mL. There was a mean of 1.4 prior aspiration attempts (range, 0-3). Mean injected ethanol volume was 39 mL (range, 8-60 mL) for a mean of 26â ±â 5 minutes. Seromas recurred in 85% (17/20) of cases, and repeat aspiration was performed in 35% (6/17). The mean recurrence time was 34â ±â 29 days. The recurrent seromas were 31% smaller (mean, 80â ±â 48 mL). Only a smaller pre-ablation seroma was associated with successful ablation (Pâ <â 0.01), as the mean pre-ablation volume was 36 ± 24 mL for successful ablations and 119â ±â 56 mL for unsuccessful ablations. There were no post-procedural complications. CONCLUSION: Single-treatment ethanol sclerotherapy is typically unsuccessful in ablating breast and axillary seromas. Only a smaller pre-ablation seroma size was associated with successful ablation.

BACKGROUND. The incidence of ductal carcinoma in situ (DCIS) has steadily increased, as have concerns regarding overtreatment. Active surveillance is a novel treatment strategy that avoids surgical excision, but identifying patients with occult invasive disease who should be excluded from active surveillance is challenging. Radiologists are not typically expected to predict the upstaging of DCIS to invasive disease, though they might be trained to perform this task. OBJECTIVE. The purpose of this study was to determine whether a mixed-methods two-stage observer study can improve radiologists' ability to predict upstaging of DCIS to invasive disease on mammography. METHODS. All cases of DCIS calcifications that underwent stereotactic biopsy between 2010 and 2015 were identified. Two cohorts were randomly generated, each containing 150 cases (120 pure DCIS cases and 30 DCIS cases upstaged to invasive disease at surgery). Nine breast radiologists reviewed the mammograms in the first cohort in a blinded fashion and scored the probability of upstaging to invasive disease. The radiologists then reviewed the cases and results collectively in a focus group to develop consensus criteria that could improve their ability to predict upstaging. The radiologists reviewed the mammograms from the second cohort in a blinded fashion and again scored the probability of upstaging. Statistical analysis compared the performances between rounds 1 and 2. RESULTS. The mean AUC for reader performance in predicting upstaging in round 1 was 0.623 (range, 0.514-0.684). In the focus group, radiologists agreed that upstaging was better predicted when an associated mass, asymmetry, or architectural distortion was present; when densely packed calcifications extended over a larger area; and when the most suspicious features were focused on rather than the most common features. Additionally, radiologists agreed that BI-RADS descriptors do not adequately characterize risk of invasion, and that microinvasive disease and smaller areas of DCIS will have poor prediction estimates. Reader performance significantly improved in round 2 (mean AUC, 0.765; range, 0.617-0.852; p = .045). CONCLUSION. A mixed-methods two-stage observer study identified factors that helped radiologists significantly improve their ability to predict upstaging of DCIS to invasive disease. CLINICAL IMPACT. Breast radiologists can be trained to better predict upstaging of DCIS to invasive disease, which may facilitate discussions with patients and referring providers.

RATIONALE AND OBJECTIVES: The purpose of this study is to quantify breast radiologists' performance at predicting occult invasive disease when ductal carcinoma in situ (DCIS) presents as calcifications on mammography and to identify imaging and histopathological features that are associated with radiologists' performance. MATERIALS AND METHODS: Mammographically detected calcifications that were initially diagnosed as DCIS on core biopsy and underwent definitive surgical excision between 2010 and 2015 were identified. Thirty cases of suspicious calcifications upstaged to invasive ductal carcinoma and 120 cases of DCIS confirmed at the time of definitive surgery were randomly selected. Nuclear grade, estrogen and progesterone receptor status, patient age, calcification long axis length, and breast density were collected. Ten breast radiologists who were blinded to all clinical and pathology data independently reviewed all cases and estimated the likelihood that the DCIS would be upstaged to invasive disease at surgical excision. Subgroup analysis was performed based on nuclear grade, long axis length, breast density and after exclusion of microinvasive disease. RESULTS: Reader performance to predict upstaging ranged from an area under the receiver operating characteristic curve (AUC) of 0.541-0.684 with a mean AUC of 0.620 (95%CI: 0.489-0.751). Performances improved for lesions smaller than 2 cm (AUC: 0.676 vs 0.500; pâ¯=â¯0.002). The exclusion of microinvasive cases also improved performance (AUC: 0.651 vs 0.620; pâ¯=â¯0.005). There was no difference in performance based on breast density (pâ¯=â¯0.850) or nuclear grade (pâ¯=â¯0.270) CONCLUSION: Radiologists were able to predict invasive disease better than chance, particularly for smaller DCIS lesions (<2 cm) and after the exclusion of microinvasive disease.

PURPOSE: The purpose of this study is to quantify the relationship between author gender and publication topic, as well as the impact of gender-related research. METHODS: We reviewed all original research publications in Radiology, American Journal of Roentgenology, and Academic Radiology from 2011 through 2015. For each article, we recorded the gender of all authors and the last author H-index, years in practice, and academic rank. The total citations and citation rate (citations per year) were calculated for each article. Articles were categorized as gender-neutral, women's health, or men's health. RESULTS: There were 1,934 publications involving 11,657 authors. Women represented 30% of first, 25% of last, and 28% of all authors. There were 1,596 (83%) gender-neutral, 276 (14%) women's health, and 61 (3%) men's health articles. Women's health articles were associated with a female first (odds ratio [OR] = 5.0, P < .001) and last author (OR = 6.4, P < .001), as well as more female authors (male = 1.4, female = 3.6, P < .001). Men's health articles were associated with a male first (OR = 2.6, P = .004) and last author (OR = 2.2, P = .03). There were significantly more citations for men's (43.5 ± 54.9, P < .001) and women's health (27.6 ± 37.5, P < .008) articles than gender-neutral articles (21.9 ± 28.9). Similarly, the article citation rate was higher for men's (10.6 ± 11.3, P < .001) and women's health (6.8 ± 8.5, P = .004) articles than gender-neutral publications (5.3 ± 7.0). CONCLUSION: Radiology researchers publish more often on topics related to their own gender. Furthermore, men's and women's health research generates more citations than gender-neutral research.

BACKGROUND: Preliminary work has demonstrated that background parenchymal enhancement (BPE) assessed by radiologists is predictive of future breast cancer in women undergoing high-risk screening MRI. Algorithmically assessed measures of BPE offer a more precise and reproducible means of measuring BPE than human readers and thus might improve the predictive performance of future cancer development. PURPOSE: To determine if algorithmically extracted imaging features of BPE on screening breast MRI in high-risk women are associated with subsequent development of cancer. STUDY TYPE: Case-control study. POPULATION: In all, 133 women at high risk for developing breast cancer; 46 of these patients developed breast cancer subsequently over a follow-up period of 2 years. FIELD STRENGTH/SEQUENCE: 5 T or 3.0 T T1 -weighted precontrast fat-saturated and nonfat-saturated sequences and postcontrast nonfat-saturated sequences. ASSESSMENT: Automatic features of BPE were extracted with a computer algorithm. Subjective BPE scores from five breast radiologists (blinded to clinical outcomes) were also available. STATISTICAL TESTS: Leave-one-out crossvalidation for a multivariate logistic regression model developed using the automatic features and receiver operating characteristic (ROC) analysis were performed to calculate the area under the curve (AUC). Comparison of automatic features and subjective features was performed using a generalized regression model and the P-value was obtained. Odds ratios for automatic and subjective features were compared. RESULTS: The multivariate model discriminated patients who developed cancer from the patients who did not, with an AUC of 0.70 (95% confidence interval: 0.60-0.79, P < 0.001). The imaging features remained independently predictive of subsequent development of cancer (P < 0.003) when compared with the subjective BPE assessment of the readers. DATA CONCLUSION: Automatically extracted BPE measurements may potentially be used to further stratify risk in patients undergoing high-risk screening MRI. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 5 J. Magn. Reson. Imaging 2019;50:456-464.

RATIONALE AND OBJECTIVES: To determine if background parenchymal enhancement (BPE) on screening breast magnetic resonance imaging (MRI) in high-risk women correlates with future cancer. MATERIALS AND METHODS: All screening breast MRIs (n = 1039) in high-risk women at our institution from August 1, 2004, to July 30, 2013, were identified. Sixty-one patients who subsequently developed breast cancer were matched 1:2 by age and high-risk indication with patients who did not develop breast cancer (n = 122). Five fellowship-trained breast radiologists independently recorded the BPE. The median reader BPE for each case was calculated and compared between the cancer and control cohorts. RESULTS: Cancer cohort patients were high-risk because of a history of radiation therapy (10%, 6 of 61), high-risk lesion (18%, 11 of 61), or breast cancer (30%, 18 of 61); BRCA mutation (18%, 11 of 61); or family history (25%, 15 of 61). Subsequent malignancies were invasive ductal carcinoma (64%, 39 of 61), ductal carcinoma in situ (30%, 18 of 61) and invasive lobular carcinoma (7%, 4of 61). BPE was significantly higher in the cancer cohort than in the control cohort (P = 0.01). Women with mild, moderate, or marked BPE were 2.5 times more likely to develop breast cancer than women with minimal BPE (odds ratio = 2.5, 95% confidence interval: 1.3-4.8, P = .005). There was fair interreader agreement (κ = 0.39). CONCLUSIONS: High-risk women with greater than minimal BPE at screening MRI have increased risk of future breast cancer.

RATIONALE AND OBJECTIVES: Women are under-represented in radiology, but the implications of this under-representation are poorly understood. Therefore, the purpose of this study was to determine if articles published by women in major radiology journals were more collaborative. MATERIALS AND METHODS: Following an institutional review board exemption, we reviewed all original research articles in Radiology, in the American Journal of Roentgenology, and in Academic Radiology from 2011 to 2015. For each article, the gender of the first and the last authors and proxy measures of collaboration were recorded, including the total number of authors, female authors, departments, and institutions. Nominal logistic regression analysis was used to test for associations while controlling for confounders. RESULTS: There were 1934 articles analyzed. Female first and last authors represented 30.2% (585 of 1934) and 24.4% (473 of 1934) of the articles, respectively. A female first author was associated with more female last authors (36% vs 20%, P < .001), total female authors (2.9 vs 1.2, P < .001), and departments (3.3 vs 3.0, P < .001). Similarly, a female last author was associated with more female first authors (44% vs 26%, P = .001), total female authors (3.1 vs 1.2, P < .001), departments (3.5 vs 3.0 P < .001), and institutions (2.3 vs 1.9, P = .006). Each additional female author increased the mean number of institutions by 0.33 and departments by 0.46 on linear regression. First- or last-author gender was not associated with total authors (P = .17). CONCLUSIONS: Original research articles published with a female first or last author were associated with more departments and institutions, but not with the total number of authors, suggesting that women engage in some metrics of more collaborative research.

RATIONALE AND OBJECTIVES: Women make up half of American medical school graduates, but remain underrepresented among radiologists. This study sought to determine whether workforce gender disparities exist in other countries, and to identify any country-specific indices associated with increased female representation. MATERIALS AND METHODS: In this cross-sectional study, 95 professional radiology organizations in 75 countries were contacted via email to provide membership statistics, including proportion of female members, female members aged 35 or under, and women in society leadership positions. Country-specific metrics collected included gross domestic product, Gini index, percent female medical school enrollment, and Gender Development Index for the purposes of univariate multiple regression analysis. RESULTS: Twenty-nine organizations provided data on 184,888 radiologists, representing 26 countries from Europe (n = 12), North America (n = 2), Central/South America (n = 6), Oceania (n = 2), Asia (n = 3), and Africa (n = 1) for a response rate of 34.7% (26/75). Globally, 33.5% of radiologists are female. Women constitute a higher proportion of younger radiologists, with 48.5% of radiologists aged 35 or under being female. Female representation in radiology is lowest in the United States (27.2%), highest in Thailand (85.0%), and most variable in Europe (mean 40.1%, range 28.8%-68.9%). The proportion of female radiologists was positively associated with a country's Gender Development Index (P = .006), percent female medical student enrollment (P = .001), and Gini index (P = .002), and negatively associated with gross domestic product (P = .03). CONCLUSIONS: Women are underrepresented in radiology globally, most notably in the United States. Countries with greater representation of women had higher gender equality and percent female medical school enrollment, suggesting these factors may play a role in the gender gap.

RATIONALE AND OBJECTIVES: The purpose of this study is to determine how the motivations to pursue a career in radiology differ by gender. In addition, the influence of medical school radiology education will be assessed. MATERIALS AND METHODS: Radiology applicants to our institution from the 2015-2016 interview season were offered an online survey in February 2016. Respondents scored the influence of 24 aspects of radiology on their decision to pursue radiology. Comparisons were made between male and female respondents. Respondents were also asked the type of medical school radiology education they received and to score the influence this experience had on their decision to pursue radiology. RESULTS: There were 202 total respondents (202/657) including 47 women and 155 men. Compared to men, the following factors had a more negative impact on women: flexible work hours (P = 0.04), work environment (P = 0.04), lifestyle (P = 0.04), impact on patient care (P = 0.05), high current debt load (P = 0.02), gender distribution of the field (P = 0.04), and use of emerging/advanced technology (P = 0.02). In contrast, women felt more favorably about the opportunities for leadership (P = 0.04) and research (P < 0.01). Dedicated radiology exposure was as follows: 20% (n = 20) none, 48% (n = 96) preclinical exposure, 55% (n = 111) elective rotation, and 18% (n = 37) core rotation. More intensive radiology exposure via a core rotation had a significantly positive impact on the decision to pursue radiology (P < 0.01). CONCLUSIONS: Male and female radiology applicants are motivated by different aspects of radiology, which may influence residency recruitment practices. In addition, more intensive radiology exposure has a net positive impact on the decision to pursue radiology.

PURPOSE: To determine the gender distribution of radiology residency programs and identify associations with radiology departmental factors. METHODS: The residency programs affiliated with the top 50 research medical school from US News and World Report were identified. The gender of all radiology residency graduates from each program from 2011 to 2015 were collected. Radiology departmental factors were collected: gender of chairperson, gender of program director, gender of faculty, geographic location, and city population of the residency program. The median percentage of female radiology faculty and residents were calculated and classified as above or below the median. Comparisons were made between residency programs and departmental factors via a Pearson χ2 univariate test or logistic regression. RESULTS: There were 618 (27.9%) female and 1,598 (72.1%) male residents in our study, with a median female representation of 26.4% in each program. Programs with a female residency program director were significantly more likely to have an above-median percentage of female residents versus a male program director (68.4% versus 38.7%, P = .04). Programs in the Northeast (70.6%) and West (70.0%) had higher above-median female representation than the South (10.0%) and Midwest (38.5%, P < .01). There was no association with city population size (P = .40), gender of faculty (P = .40), residency size (P = .91), or faculty size (P = .15). CONCLUSION: Radiology residency programs with a female residency program director and those in the Northeast or West have a greater concentration of female residents. Residency programs that aim to increase female representation should investigate modifiable factors that can improve their recruitment practices.

This study investigated how time from breast biopsy recommendation to biopsy procedure affected pre-biopsy anxiety ( N = 140 women), and whether the relationship between wait time and anxiety was affected by psychosocial factors (chronic life stress, traumatic events, social support). Analyses showed a significant interaction between wait time and chronic life stress. Increased time from biopsy recommendation was associated with greater anxiety in women with low levels of life stress. Women with high levels of life stress experienced increased anxiety regardless of wait time. These results suggest that women may benefit from shorter wait times and receiving strategies for managing anxiety.

PURPOSE: To evaluate the impact of guided meditation and music interventions on patient anxiety, pain, and fatigue during imaging-guided breast biopsy. METHODS: After giving informed consent, 121 women needing percutaneous imaging-guided breast biopsy were randomized into three groups: (1) guided meditation; (2) music; (3) standard-care control group. During biopsy, the meditation and music groups listened to an audio-recorded, guided, loving-kindness meditation and relaxing music, respectively; the standard-care control group received supportive dialogue from the biopsy team. Immediately before and after biopsy, participants completed questionnaires measuring anxiety (State-Trait Anxiety Inventory Scale), biopsy pain (Brief Pain Inventory), and fatigue (modified Functional Assessment of Chronic Illness Therapy-Fatigue). After biopsy, participants completed questionnaires assessing radiologist-patient communication (modified Questionnaire on the Quality of Physician-Patient Interaction), demographics, and medical history. RESULTS: The meditation and music groups reported significantly greater anxiety reduction (P values < .05) and reduced fatigue after biopsy than the standard-care control group; the standard-care control group reported increased fatigue after biopsy. The meditation group additionally showed significantly lower pain during biopsy, compared with the music group (P = .03). No significant difference in patient-perceived quality of radiologist-patient communication was noted among groups. CONCLUSIONS: Listening to guided meditation significantly lowered biopsy pain during imaging-guided breast biopsy; meditation and music reduced patient anxiety and fatigue without compromising radiologist-patient communication. These simple, inexpensive interventions could improve women's experiences during core-needle breast biopsy.

OBJECTIVE: The purposes of this study were to evaluate the frequency, follow-up compliance, and cancer rate of MRI BI-RADS category 3 lesions and to determine the cancer rate for individual BI-RADS descriptors. MATERIALS AND METHODS: A retrospective review was conducted of breast MRI examinations with an assessment of probably benign (BI-RADS category 3) from among 4279 consecutive breast MRI examinations performed from January 2005 through December 2009. The review revealed 282 (6.6%) examinations with 332 lesions defined as BI-RADS 3. Pathologic results, 2 years of follow-up imaging findings, or both were reviewed. The frequency of BI-RADS 3 assessments, follow-up imaging compliance, and cancer yield were calculated. Three fellowship-trained breast imagers reevaluated all lesions and recorded descriptors from the MRI lexicon of the fifth edition of the BI-RADS atlas. The distribution and likelihood of malignancy for each descriptor were calculated. RESULTS: The follow-up compliance rate was 84.3% (280/332), and the malignancy rate was 4.3% (12/280). There were 50 (17.9%) individual foci, 61 (21.8%) multiple foci, 74 (26.4%) masses, and 95 (33.9%) nonmass enhancement lesions. Masses were most commonly oval (59.5% [44/74]), circumscribed (75.7% [56/74]), and homogeneously enhancing (43.2% [32/74]). Nonmass enhancement was most commonly focal (57.9% [55/95]) with heterogeneous enhancement (53.7% [51/95]) Most of the lesions had persistent kinetics (74.3% [208/280]). The background parenchymal enhancement was most commonly mild (51.1% [143/280]). CONCLUSION: MRI BI-RADS category 3 is not frequently used, and the levels of patient compliance with follow-up imaging are acceptable. The cancer yield for probably benign lesions is greater for MRI-detected than for mammographically detected lesions, especially for specific BI-RADS descriptors.

PURPOSE: The purpose of this study is to investigate the association between breast cancer recurrence-free survival and breast magnetic resonance imaging (MRI) tumor enhancement dynamics which are quantified semi-automatically using computer algorithms. METHODS: In this retrospective IRB-approved study, we analyzed data from 275 breast cancer patients at a single institution. Recurrence-free survival data were obtained from the medical record. Routine clinical pre-operative breast MRIs were performed in all patients. The tumors were marked on the MRIs by fellowship-trained breast radiologists. A previously developed computer algorithm was applied to the marked tumors to quantify the enhancement dynamics relative to the automatically assessed background parenchymal enhancement. To establish whether the contrast enhancement feature quantified by the algorithm was associated with recurrence-free survival, we constructed a Cox proportional hazards regression model with the computer-extracted feature as a covariate. We controlled for tumor grade and size (major axis length), patient age, patient race/ethnicity, and menopausal status. RESULTS: The analysis showed that the semi-automatically obtained feature quantifying MRI tumor enhancement dynamics was independently predictive of recurrence-free survival (p=0.024). CONCLUSION: Semi-automatically quantified tumor enhancement dynamics on MRI are predictive of recurrence-free survival in breast cancer patients.

RATIONALE AND OBJECTIVES: To assess how well radiologists visualize relevant features of lesions seen with automated breast volumetric scanning (ABVS) in comparison to hand-held breast ultrasound in women going to breast biopsy. MATERIALS AND METHODS: Twenty-five subjects were recruited from women who were scheduled to undergo a breast biopsy for at least one Breast Imaging-Reporting and Data System four or five lesion identified in a diagnostic setting. In this institutional review board-approved study, the subjects underwent imaging of the breast(s) of concern using a dedicated system that allowed both hand-held breast ultrasound and ABVS. Five experienced breast radiologists reviewed the 30 lesions in 25 subjects in a reader study. Each reader was asked to specify the lesion type, size, imaging features, Breast Imaging-Reporting and Data System, and suspicion of malignancy and to compare the lesion characteristics of shape and margins between the two modalities. RESULTS: Seven (23.3%) masses were malignant and 23 (76.4%) were benign. Across all lesions regardless of size or final pathology, there was no significant difference in sensitivity or specificity (P > .15) between the two modalities. For malignant lesions, the reader visualization confidence scores between the two ultrasound modalities were not significantly different (P > .1). However, analysis for nonmalignant cases showed a statistically significant increase in reader visualization confidence in lesion shape and margins (P < .001). CONCLUSIONS: Radiologists showed increased confidence in visualization of benign masses and equal confidence in suspicious masses with ABVS imaging. This information could help decrease the need for additional hand-held imaging after automated whole breast ultrasound.

OBJECTIVE: The purpose of this study was to assess the interobserver variability of users of the MRI lexicon in the fifth edition of the BI-RADS atlas. MATERIALS AND METHODS: Three breast imaging specialists reviewed 280 routine clinical breast MRI findings reported as BI-RADS category 3. Lesions reported as BI-RADS 3 were chosen because variability in the use of BI-RADS descriptors may influence which lesions are classified as probably benign. Each blinded reader reviewed every study and recorded breast features (background parenchymal enhancement) and lesion features (lesion morphology, mass shape, mass margin, mass internal enhancement, nonmass enhancement distribution, nonmass enhancement internal enhancement, enhancement kinetics) according to the fifth edition of the BI-RADS lexicon and provided a final BI-RADS assessment. Interobserver variability was calculated for each breast and lesion feature and for the final BI-RADS assessment. RESULTS: Interobserver variability for background parenchymal enhancement was fair (ĸ = 0.28). There was moderate agreement on lesion morphology (ĸ = 0.53). For masses, there was substantial agreement on shape (ĸ = 0.72), margin (ĸ = 0.78), and internal enhancement (ĸ = 0.69). For nonmass enhancement, there was substantial agreement on distribution (ĸ = 0.69) and internal enhancement (ĸ = 0.62). There was slight agreement on lesion kinetics (ĸ = 0.19) and final BI-RADS assessment (ĸ = 0.11). CONCLUSION: There is moderate to substantial agreement on most MRI BI-RADS lesion morphology descriptors, particularly mass and nonmass enhancement features, which are important predictors of malignancy. Considerable disagreement remains, however, among experienced readers whether to follow particular findings.
