OBJECTIVE:Understand radiologists' opinions regarding remote breast imaging and determine whether having home workstations is associated with greater job satisfaction or less burnout. METHODS:A 43-question survey on remote breast imaging was distributed to Society of Breast Imaging members (July 6 to August 2, 2023). Questions regarding job satisfaction and burnout were included. Pearson's chi-squared tests compared demographic variables and responses. Multiple-variable logistic regression assessed associations between home workstations and job satisfaction or burnout. RESULTS:In total, 424 surveys were completed (response rate 13%, 424/3244). Among the third (31%, 132/424) of breast imaging radiologists with home workstations, top motivations included flexibility/work-life balance (67%; 88/132) and decreased commute time (51%, 67/132). Most felt that working from home improved their efficiency (65%, 86/132). Perceived drawbacks among all breast imaging radiologists included the inability to perform US or physical examination (71%, 300/424) and impaired patient contact (47%, 198/424). Most (57%, 240/424) wished for more breast imaging remote reading opportunities, and one-third (32%, 136/424) saw themselves in a 100% remote reading practice in the future. The majority (60%, 228/388) felt that remote reading would majorly or moderately improve radiologist wellness, but no significant association was found between having home workstations and job satisfaction (P = .301) or burnout (P = .140). CONCLUSION/CONCLUSIONS:The majority of breast imaging radiologists want more opportunities to work remotely, perceiving that it improves work-life balance and efficiency, albeit at the expense of patient contact. However, those currently working from home did not have higher job satisfaction or lower burnout.

Routine screening substantially reduces the risk of mortality and morbidity of breast cancer with early detection. Multiple different imaging modalities may be used to screen for breast cancer. Screening recommendations differ based on an individual's risk of developing breast cancer. Numerous factors contribute to breast cancer risk, which is frequently divided into three major categories: average, intermediate, and high risk. For patients assigned female at birth with native breast tissue, mammography and digital breast tomosynthesis are recommended for breast cancer screening in all risk categories. In high-risk patients, screening with breast MRI is recommended starting as early as 25 to 30 years of age and mammography and digital breast tomosynthesis with a variable starting age between 25 and 40 years of age, depending on the type of risk. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Breast cancer screening recommendations have been established historically for women, but, have been less clearly outlined for men. For average-risk men and younger men less than 25 year of age, imaging is not usually appropriate as a screening test for breast cancer. For men of higher-than-average risk, screening with mammography as annual surveillance imaging is usually appropriate.

OBJECTIVE:To assess the current perceptions of breast imaging staffing shortages and contributing factors among breast imaging radiologists. METHODS:A survey assessing current perception of breast radiologists regarding breast imaging-specific staffing shortages and contributing factors was developed by the Patient Care and Delivery Committee of the Society of Breast Imaging (SBI) and emailed to SBI active physician members. Bivariable analysis (chi-squared, t test) was performed between the survey demographics and survey response questions of interest. RESULTS:There were 309 responses (response rate of 15.7%). Most respondents perceived their practices to be short-staffed for breast radiologists (79%, 239/302), US technologists (74%, 216/290), mammography technologists (70%, 211/301), and support staff (66%, 201/302). Of the respondents who indicated they were short-staffed for breast imaging radiologists, 92% (226/246) believed it was due to insufficient number of radiologists, 67% (164/246) thought it was due to increase in volume, and 63% (154/246) attributed it to both increase in volume and insufficient number of breast imaging radiologists. Practices were more likely to be short-staffed if they had more practice sites (mean, 8.2 ± 7.1 vs 6.4 ± 8.4; P = .002), had fewer breast imaging radiologists (mean, 10.1 ± 9.6 vs 11.3 ± 11.5; P = .009), and were academic practices (35.1% vs 25.7%; P = .028). CONCLUSIONS:Most breast imaging radiologists perceive their current breast imaging practices to be short-staffed for radiologists, mammography technologists, US technologists, and support staff. Understanding contributing factors is crucial to addressing root causes and mitigating impact on patient care and burnout across breast imaging team members.

We used focus groups of radiologists who led the implementation of contrast-enhanced mammography (CEM) in their practice to identify barriers and strategies for adoption. Members of the Society of Breast Imaging in the United States who served as lead on CEM implementation were invited to participate in 2 separate focus groups. Ten breast imaging radiologists with varied geographic and practice type (60% academic, 30% private, and 10% community practice) participated. There were 4 major themes identified: patient selection, workflow, contrast, and billing. Patient selection varied widely among practices, with some limiting CEM to patients unable to obtain MRI and others routinely using CEM for diagnostic workup. Lack of Food and Drug Administration approval limited screening applications in some practices. Workflow challenges were numerous, and site-specific solutions were developed for ordering, scheduling, staffing, and intravenous access. There were universal concerns regarding contrast, including safe administration, response to reactions, and biopsy planning for findings only visible on CEM. Contrast reaction training, including conducting mock codes at some practices, helped alleviate concerns of the radiologists and technologists. Finally, billing was an administrative hurdle that influenced patient selection. Ample preparation is needed to successfully start a CEM program with particular attention to patient selection, workflow, contrast administration/reactions, and billing.

OBJECTIVE:Assess current practices and plans regarding home workstations and remote diagnostic breast imaging in the United States. METHODS:A 43-question survey relating to remote breast imaging was distributed to Society of Breast Imaging members from July 6, 2023, through August 2, 2023. A descriptive summary of responses was performed. Pearson's chi-squared test was used to compare demographic variables of respondents and questions of interest. RESULTS:In total, 424 surveys were completed (response rate 13%, 424/3244). One-third of breast imaging radiologists (31%, 132/424) reported reading examinations from home or a personal remote site for a median of 25% of their clinical time. The most common types of examinations read from home were screening mammography (90%, 119/132), screening US (58%, 77/132), diagnostic mammography and MRI (both 53%, 70/132), and diagnostic US (49%, 65/132). Respondents from private practices were more likely than those from academic practices to read diagnostic imaging from home (67%, 35/52 vs 29%, 15/52; P <.001). Respondents practicing in the West were less likely to read breast imaging examinations from home compared with those in other geographic regions (18%, 12/67 vs 28%-43% for other regions; P = .023). No differences were found among respondents' overall use of home workstations based on age, gender, or having dependents. Most respondents (75%, 318/424) felt that remote breast reading would be a significant practice pattern in the future. CONCLUSION/CONCLUSIONS:Home workstations for mammography and remote diagnostic breast imaging are a considerable U.S. practice pattern. Further research should explore radiologist preferences regarding remote breast imaging and its impact on clinical care and radiologist well-being.

Invasive lobular carcinoma (ILC) is the second-most common histologic subtype of breast cancer, constituting 5% to 15% of all breast cancers. It is characterized by an infiltrating growth pattern that may decrease detectability on mammography and US. The use of digital breast tomosynthesis (DBT) improves conspicuity of ILC, and sensitivity is 80% to 88% for ILC. Sensitivity of mammography is lower in dense breasts, and breast tomosynthesis has better sensitivity for ILC in dense breasts compared with digital mammography (DM). Screening US identifies additional ILCs even after DBT, with a supplemental cancer detection rate of 0 to 1.2 ILC per 1000 examinations. Thirteen percent of incremental cancers found by screening US are ILCs. Breast MRI has a sensitivity of 93% for ILC. Abbreviated breast MRI also has high sensitivity but may be limited due to delayed enhancement in ILC. Contrast-enhanced mammography has improved sensitivity for ILC compared with DM, with higher specificity than breast MRI. In summary, supplemental screening modalities increase detection of ILC, with MRI demonstrating the highest sensitivity.

Beyond the technical aspects, success and long-term patient outcomes of image-guided breast biopsies depend on the overall patient experience. Patient experience in turn is influenced by intangible factors, such as environmental features during the procedure; patient-centered communication prior to, during, and subsequent to the procedure; and management of expectations and biopsy complications. Here, we review evidence-based literature and results of a national Society of Breast Imaging survey on approaches to both mitigate and manage common image-guided core biopsy complications as well as nontechnical strategies to improve the patient biopsy experience.

Image-guided biopsy is an integral step in the diagnosis and management of suspicious image-detected breast or axillary lesions, allowing for accurate diagnosis and, if indicated, treatment planning. Tissue sampling can be performed under guidance of a full spectrum of breast imaging modalities, including stereotactic, tomosynthesis, sonographic, and MRI, each with its own set of advantages and limitations. Procedural planning, which includes consideration of technical, patient, and lesion factors, is vital for diagnostic accuracy and limitation of complications. The purpose of this paper is to review and provide guidance for breast imaging radiologists in selecting the best procedural approach for the individual patient to ensure accurate diagnosis and optimal patient outcomes. Common patient and lesion factors that may affect successful sampling and contribute to postbiopsy complications are reviewed and include obesity, limited patient mobility, patient motion, patients prone to vasovagal reactions, history of anticoagulation, and lesion location, such as proximity to vital structures or breast implant.

OBJECTIVE:The availability of same-day services in breast imaging is an important topic given potential advantages for timely diagnoses and patient experiences, but there are potential barriers that lead facilities to not offer these services. We sought to understand current practice patterns and radiologist perspectives on offering same-day services. METHODS:The Society of Breast Imaging (SBI) Patient Care & Delivery Committee developed a 19-question survey that was emailed to all 3449 active members of the SBI in May 2023. An exemption from the institutional review board was obtained at the lead author's institution. The survey consisted of 19 questions that were designed to understand the scope, perceptions, barriers, and logistics of same-day services. Comparisons were made between responses for offering same-day services (screening interpretation, diagnostic examinations, biopsies) and respondent demographics. RESULTS:A total of 437 American and Canadian members participated, yielding a response rate of 12.7%. Respondents were most commonly in private practice (43.0%, 188/437), working in an outpatient medical center-based clinic (41.9%, 183/437), and without trainees (64.5%, 282/437). Respondents estimated 12.1% of screening examinations were interpreted while patients waited, which was significantly more common in free-standing breast imaging clinics (P = .028) and practices without trainees (P = .036). Respondents estimated 15.0% of diagnostic examinations were performed same day, which was more common in academic and private practices (P = .03) and practices without trainees (P = .01). Respondents estimated 11.5% of biopsies were performed the same day as the recommendation, which had no association with practice type/context, presence of trainees, number of mammography units, number of radiologists, or number of technologists. Long patient travel distance and limited patient mobility were the most cited reasons for offering patients same-day services. CONCLUSION/CONCLUSIONS:Offering same-day breast imaging services varies among institutions and may be influenced by factors such as practice context and type and the presence of trainees.
