The impact of the COVID-19 mammography screening hiatus as well as of post-hiatus efforts promoting restoration of elective healthcare on breast cancer detection patterns and stage distribution is unknown.Newly diagnosed breast cancer patients (2019-2021) at the New York Presbyterian (NYP) Hospital Network were analyzed. Chi-square and student's t-test compared characteristics of patients presenting before and after the screening hiatus.A total of 2137 patients were analyzed. Frequency of screen-detected and early-stage breast cancer declined post-hiatus (59.7%), but returned to baseline (69.3%). Frequency of screen-detected breast cancer was lowest for African American (AA) (57.5%) and Medicaid patients pre-hiatus (57.2%), and this disparity was reduced post-hiatus (65.3% for AA and 63.2% for Medicaid).The return to baseline levels of screen-detected cancer, particularly among AA and Medicaid patients suggest that large-scale breast health education campaigns may be effective in resuming screening practices and in mitigating disparities.

Purpose To test the feasibility of using quantitative transport mapping (QTM) method, which is based on the inversion of transport equation using spatial deconvolution without any arterial input function, for automatically postprocessing dynamic contrast enhanced MRI (DCE-MRI) to differentiate malignant and benign breast tumors. Materials and methods Breast DCE-MRI data with biopsy confirmed malignant (n = 13) and benign tumors (n = 13) was used to assess QTM velocity (|u|) and diffusion coefficient (D), volume transfer constant (Ktrans), volume fraction of extravascular extracellular space (Ve) from kinetics method, and traditional enhancement curve characteristics (ECC: amplitude A, wash-in rate α, wash-out rate β). A Mann-Whitney U test and receiver operating characteristic curve (ROC) analysis were performed to assess the diagnostic performance of these parameters for distinguishing between benign and malignant tumors. Results Between malignant and benign tumors, there was a significant difference in |u| and Ktrans, (p = 0.0066, 0.0274, respectively), but not in D, Ve, A, α and β (p = 0.1119, 0.2382, 0.4418,0.2592 and 0.9591, respectively). ROC area-under-the-curve was 0.82, 0.75 (95% confidence level 0.60–0.95, 0.51–0.90) for |u| and Ktrans, respectively. Conclusion QTM postprocesses DCE-MRI automatically through deconvolution in space and time to solve the inverse problem of the transport equation. Comparing with traditional kinetics method and ECC, QTM method showed better diagnostic accuracy in differentiating benign from malignant breast tumors in this study.

With the Pfizer-BioNTech, Moderna, and now Johnson and Johnson COVID-19 vaccines readily available to the general population, the appearance of vaccine-induced axillary adenopathy on imaging has become more prevalent. We are presenting follow up to the first reported four cases of vaccine induced unilateral axillary adenopathy on imaging to our knowledge, which demonstrate expected self-resolving adenopathy. Our hope is that by providing this follow-up and reviewing current management guidelines, clinicians as well as patients will appreciate that this is an expected, benign, and self-resolving finding. In addition, we hope to quell any vaccine hesitancy brought about by recent mainstream media attention to this topic and ultimately empower patients to receive both the COVID-19 vaccine and undergo routine screening mammography, as both are vital to their health.

Physician burnout is a recognized problem within medicine and its prevalence appears to be increasing. The symptoms include three major components; exhaustion, depersonalization and feeling a lack of accomplishment. The presence of burnout can have major professional and personal consequences. While there has been much commentary on the impact of burnout, little has been published addressing ways to prevent and resolve the issue. Our department has taken a novel and individualized approach to lower burnout. This includes allowing faculty to personalize their schedules as demonstrated by the perspectives of four breast imaging faculty. We as physicians are as diverse as the patient population we treat which needs to be recognized when addressing solutions to burnout. We propose that most practices and departments can find meaningful ways to allow physicians to increase their sense of autonomy through flexibility and control in scheduling. Having leadership open to unique and sometimes unconventional approaches enables a mutually beneficial culture of respect, productivity, and wellness.

Screening mammography improves breast cancer survival through early detection, but Triple Negative Breast Cancer (TNBC) is more difficult to detect on mammography and has lower survival compared to non-TNBC, even when detected at early stages. TNBC is twice as common among African American (AA) compared to White American (WA) women, thereby contributing to the 40% higher breast cancer mortality rates observed in AA women. The role of screening mammography in addressing breast cancer disparities is therefore worthy of study.Outcomes were evaluated for TNBC patients treated in the prospectively-maintained databases of academic cancer programs in two metropolitan cities of the Northeast and Midwest, 1998-2018.Of 756 TNBC cases, 301 (39.8%) were mammographically screen-detected. 46% of 189 AA and 38.5% of 460 WA patients had screen-detected TNBC (p = 0.16). 25.3% of 257 TNBC cases ≤50 years old had screen-detected disease compared to 47.3% of 499 TNBC cases50 years old (p 0.0001). 220/301 (73.1%) screen-detected TNBC cases were T1 lesions versus 118/359 (32.9%) non-screen-detected cases (p 0.0001). Screen-detected TNBC was more likely to be node-negative (51.9% v. 40.4%; p 0.0001). Five-year overall survival was better in screen-detected TNBC compared to nonscreen-detected TNBC (92.8% v. 81.5%; p 0.0001) in the entire cohort. The magnitude of this effect was most significant among AA patients (Fig. 1). Screening-related survival patterns were similar among AA and WA patients in both cities.Data from two different cities demonstrates the value of screening mammography to mitigate breast cancer disparities in AA women through the early detection of TNBC.

High-density foci within axillary lymph nodes are associated with a number of potential diagnoses. In this case series, we present four tattooed patients who had mammographic findings that demonstrated high-density material in axillary lymph nodes, indicative of tattoo pigment migration. The aim of presenting these cases is to highlight the importance of recognizing such pigment migration in order to help breast radiologists form an appropriate differential diagnosis that might include this entity.

The tent sign is a subtle mammographic finding that is not well delineated in current literature. It refers to localized retraction of the breast parenchyma causing a characteristic inverted “V” shape, or tent sign. It can often be the only indication that an underlying malignancy exists. We present the case of a 50 year-old female who presented on screening mammogram with a tent sign with pathology yielding invasive carcinoma.

To determine which modalities [2D mammography (2D), digital breast tomosynthesis (DBT), whole breast sonography (WBS)] are optimal for screening depending on breast density.Institutional retrospective cohort study of 2013 screening mammograms (16,789), sorted by modalities and density.Cancer detection is increased by adding WBS to 2D (P=.02) for the overall study population. Recall rate was lowest with 2D+DBT (10.2%, P.001) and highest with 2D+DBT+WBS (23.6%, P.001) for the overall study population as well.Women with dense and nondense breasts benefit from reduced recall rate with the addition of DBT; however, this benefit is negated with the addition of WBS.

Increasingly, states are mandating notification to patients if they are found to have dense breast tissue. Information describes the increased risk of cancer and limitations of mammography for this patient group. Such notification often creates anxiety and results in uncertainty as no evidence-based guidelines for additional screening of dense breasts are available. Through an organized consultation service, patients and physicians were provided consultations with radiologists in order to ensure an appropriate screening plan based on individualized histories and preferences. This manuscript describes our dense breast consultation program, examines initial data, and provides lessons for practices interested in providing similar service.

Due to an increasing number of breast cancer diagnoses in younger women anecdotally noted at our institution, we conceived of this study %was to retrospectively review the records of women diagnosed with breast cancer under the age of 40 for potentially alterable versus unalterable risk factors in their history. Between 2007 and 2013, there were 52 patients less than 40 years of age with breast cancer at our institution: 79% (41/52) presented with a clinical abnormality (palpable mass, nipple discharge or inversion) and 21% (11/52) were asymptomatic but diagnosed on early screening mammograms. Seventy-five percent (39/52) of the cancers had an invasive component and 87% (45/52) were intermediate to high grade. Sixty percent (31/52) of subjects had stage 0 or I disease, but 40% (21/52) had later stage disease (stage II or greater). The vast majority of the cancers were ER+ (82%) and PR+ (78%). Fifty-six percent (28/50; 2 unknown) of the subjects had a documented history of hormonal contraception. Fifty-three percent (27/51; 1 unknown) of had no family history of breast cancer whatsoever, and 80% (41/51) had no family history of breast cancer in a first degree relative. Six were positive for BRCA 1, 2, or a variant (6/52 = 12%).

ContextRadial scars are benign sclerosing lesions that are routinely excised when diagnosed in a needle core biopsy. Optimal management for patients with incidental and small (≤5 mm) radial scars is uncertain.ObjectiveTo assess pathologic upgrade of radial scars diagnosed in needle core biopsy samples and identify a subset of patients who could benefit from conservative management.DesignPatients with a diagnosis of radial scar in a needle core biopsy who underwent excision of the biopsied area were identified. Radial scars greater than 5 mm in size and those with coexisting atypia, carcinoma, and papillary lesions were excluded. After histologic-radiographic correlation, rates of pathologic upgrade were assessed.ResultsSeventy-seven radial scars diagnosed in 66 patients were included. Overall, 9 of 77 (12%) showed upgrade to a high-risk lesion (6 lobular carcinoma in situ, 2 atypical ductal hyperplasia, 1 atypical lobular hyperplasia), while none (0%) showed upgrade to invasive carcinoma or ductal carcinoma in situ. One of 22 incidental radial scars (4.5%) showed upgrade on excision versus 6 of 36 (16.7%) for radial scars considered to be the radiographic target (P = .23). Older age was associated with upgrade (P < .001).ConclusionsNo incidental or small (≤5 mm) radial scars excised revealed invasive carcinoma or ductal carcinoma in situ on excision. Provided there is good pathologic-radiologic concordance, it appears reasonable for these patients to be managed conservatively.

The purpose of this study was to review screening mammograms obtained in one practice with the primary endpoint of determining the rate of detection of breast cancer and associated prognostic features in women 40-44 and 45-49 years old.The retrospective cohort study included women in their 40s with breast cancer detected at screening from June 2014 through May 2016. The focus was on cancer detection rate, pathologic findings, and risk factors.A total of 32,762 screens were performed, and 808 biopsies were recommended. These biopsies yielded 224 breast cancers (cancer detection rate, 6.84 per 1000 screens). Women 40-49 years old had 18.8% of cancers detected; 50-59 years, 21.8%; 60-69 years, 32.6%; and 70-79 years, 21.4%. Among the 40- to 49-year-old women, women 40-44 years old underwent 5481 (16.7%) screens, had 132 biopsies recommended, and had 20 breast cancers detected (cancer detection rate, 3.6/1000). Women 45-49 years old underwent 5319 (16.2%) screens, had 108 biopsies recommended, and had 22 breast cancers detected (cancer detection rate, 4.1/1000). Thus, women 40-44 years old had 8.9% and women 45-49 years old had 9.8% of all screen-detected breast cancers. Of these only a small percentage of women with detected cancers had a first-degree relative with breast cancer (40-44 years, 15%; 45-49 years, 32%) or a BRCA mutation (40-44 years, 5%; 45-49 years, 5%), and over 60% of the cancers were invasive.Women 40-49 years old had 18.8% of all screen-detected breast cancers. The two cohorts (40-44 and 45-49 years old) had similar incidences of screen-detected breast cancer (8.9%, 9.8%) and cancer detection rates within performance benchmark standards, supporting a similar recommendation for both cohorts and the American College of Radiology recommendation of annual screening mammography starting at age 40.

Purpose The aim of this study was to determine the recall rate of screening ultrasound with automated breast volumetric scanning (ABVS) in women with dense breasts (BI-RADS density classification 3 or 4 on mammogram). Materials and Methods In this retrospective cohort study, at the end of the “first quarter” (August–October 2013) of use, our practice database was searched for all ABVS examinations performed and specifically, the positive examinations (defined as abnormal/BI-RADS 0) for which patients were recalled for additional imaging evaluation with handheld ultrasound (HHUS); the latter group was reviewed with respect to final BI-RADS and pathology if relevant. Results During the 3-month study time period, 558 ABVS studies were performed: 453 (81%) were initially BI-RADS 1 or 2 and 105 (19%) were BI-RADS 0-incomplete and recalled, corresponding with an overall recall rate of 19%; specifically, the recall rate trended down from 24.7% in August to 12.6% in October. To date, 98 of the 105 recalled women have returned for HHUS, with the resultant final BI-RADS as follows: 25/98=25% BI-RADS 1, 46/98=47% BI-RADS 2, 13/98=13% BI-RADS 3, 14/98=15% BI-RADS 4, and 0/98=0% BI-RADS 5. All biopsies performed to date of the ABVS-detected BI-RADS 4 lesions have yielded benign results, with the most common pathology being fibroadenoma. Conclusion The recall rate of screening ABVS in women with dense breasts at our institution was under 20% overall during its first quarter of use, and trended down from nearly 25% in the first month to under 13% in the third. The clinical implication is that ABVS does have a learning curve, but that is a potentially feasible way to meet the increasing demands for screening ultrasound in women with dense breasts.

In this case report, the history and imaging of two patients with invasive lobular carcinoma (ILC) in the skin are presented, followed by a discussion of both benign and malignant intradermal findings on breast ultrasound. Although the majority of dermal findings are benign, these cases are a reminder that malignancy can manifest within the skin. The purpose of presenting these cases together is to remind breast imagers of the importance of considering malignancy in the differential diagnosis of intradermal lesions on breast ultrasound, especially in special circumstances such as a personal history of breast cancer or associated clinical findings.

The purpose of the study was to review screening mammography examinations at our institution from 2007 through 2013 with the primary endpoint of determining the incidence of breast cancer and the associated histologic and prognostic features in women 75 years old or older.Patients who presented for screening mammography who ultimately received a BI-RADS assessment of category 4 or 5 for a suspicious abnormality were followed retrospectively through completion of care and were analyzed with respect to pathology results, treatment, and family history.From 2007 through 2013, 68,694 screening mammography examinations were performed. Of these screening examinations, 4424 (6.4%) were performed of patients 75 years old or older. On the basis of these examinations, 64 biopsies were recommended. Sixty biopsies were performed, and these biopsies detected 26 breast cancers. These results correspond to a breast cancer detection rate of 5.9 per 1000 screening examinations and a positive predictive value 2 (PPV2), defined as the probability of breast cancer after a BI-RADS assessment category of 4 (suspicious abnormality) or 5 (highly suggestive of malignancy), of 40.6%. Approximately 85% (22/26) of the screening-detected cancers in the women in this age group were invasive. For those with known genetic status (18 of 26), 33% had a first-degree relative with breast cancer.Although women 75 years or older accounted for less than 10% of the total screening population during the study time period, the breast cancer detection rate in this cohort was 5.9 per 1000 screening examinations, which is compatible with the American College of Radiology's recommendations, and most of these breast cancers were invasive. These results are relevant when considering appropriate age ranges for annual screening mammography.

To evaluate the ability to use breast magnetic resonance (MR) imaging to assess disease extent in patients with posterior breast masses who are suspected to have tumor invasion into underlying muscle.Nineteen patients with posterior breast masses underwent three-dimensional, gradient-echo, 1.5-T MR imaging before and after the administration of gadopentetate dimeglumine. Thirteen had deep palpable masses that were clinically determined to be fixed to the underlying chest wall. Twelve had mammographic findings that caused muscle involvement to be suspected, and seven had normal mammograms. All patients underwent surgery. MR images were reviewed and were correlated with histologic findings.Enhancing masses were identified on MR images in all 19 patients. Five (26%) of the 19 patients had masses that abutted the muscles, with obliteration of the fat plane and muscle enhancement. All five had muscle involvement at surgery. In the remaining 14 (74%) patients, no enhancement of muscle was seen; none of these had invasion of the muscle at surgery.Extension of adjacent tumor into underlying musculature was indicated by abnormal enhancement within these structures. Violation of the fat plane between tumor and muscle, without other findings, did not indicate tumor involvement of these deep structures.

The objective of our study was to review screening mammography examinations performed at our institution from 2007 through 2010 with the primary endpoint of determining the incidence of breast cancer and associated histologic and prognostic features in women in their 40s.Patients who presented for screening mammography who ultimately (i.e., after additional imaging, including diagnostic mammographic views and ultrasound) received a BI-RADS assessment of a category 4 or 5 for a suspicious abnormality were followed retrospectively through completion of care and were analyzed with respect to pathology results after biopsy, treatment, and family history.During the study period, 43,351 screening mammography examinations were performed; 1227 biopsies were recommended on the basis of those studies and yielded 205 breast cancers (cancer detection rate of 4.7 per 1000 screening examinations). These screening examinations included 14,528 (33.5%) screening examinations of patients in their 40s; 413 biopsies were recommended and yielded 39 breast cancers (39/205 = 19%) (cancer detection rate of 2.7 per 1000 screening examinations). More than 50% (21/39) of the cancers in women in their 40s were invasive. Only 8% (3/39) of the women in their 40s with screening-detected breast cancer had a first-degree relative with breast cancer.From 2007 through 2010, patients in their 40s accounted for one third of the population undergoing screening mammography and for nearly 20% of the screening-detected breast cancers--more than half of which were invasive. This information should be a useful contribution to counseling women in this age group when discussing whether or not to pursue regular screening mammography.

OBJECTIVE. The purpose of this study was to determine the benefit of routine pelvic CT in the evaluation of patients with primary breast cancer and to assess the frequency with which equivocal or abnormal findings on pelvic CT prompted the performance of additional studies or procedures that yielded results relevant to patient care. MATERIALS AND METHODS. The reports of 6628 body CT scans that included images of at least the pelvis in 2426 patients with breast cancer during a 9-year period were reviewed. The presence and sites of reported definite or probable metastases or pelvic tumors were recorded for each scan. Also, the types and results of diagnostic examinations and procedures prompted by equivocal or abnormal findings on pelvic CT were recorded. RESULTS. Pelvic metastases shown on CT were the only known site of metastasis in 13 (0.5%) of 2426 patients, and four other patients (0.2%) had new or enlarging pelvic metastases despite the presence of stable extrapelvic metastases. The pelvic metastases in these 17 patients were located in bone only in 1 1 Patients, in adnexa only in five patients, and in adnexa, endometrium, and bone in one patient. In addition, pelvic CT led to the performance of 204 additional radiologic examinations, including 186 pelvic sonographic examinations, and 50 surgical procedures; 215 (84.6%) of these 254 additional examinations and procedures yielded normal, benign, or indeterminate results. CONCLUSION. The routine use of pelvic CT in the evaluation of patients with breast cancer has an extremely low yield and often prompts performance of pelvic sonographic or surgical procedures, the results of which were rarely relevant to cancer therapy.

Our objective is to report 4 cases of incidentally discovered acoustic neuromas (ANs) and to determine the incidence of asymptomatic ANs. A prospective study of 161 consecutive patients undergoing gadolinium-enhanced MRI (Gd-MRI) at a tertiary-care university-affiliated medical center was carried out from September 1994 to April 1995. The Gd-MRI scans were performed for tentative diagnoses other than AN or sensorineural hearing loss. In 161 consecutive patients examined, no ANs were found incidentally on Gd-MRI scans. Previous studies have suggested that the incidence of occult ANs is as high as 1%. On the basis of our results, we suggest that the actual incidence may be lower. However, our study is limited by its small size and the low incidence of ANs in the general population. Also reported are the clinical and MRI characteristics of 4 patients with incidentally diagnosed ANs.
