OBJECTIVE. In recent decades, teleradiology has expanded considerably, and many radiology practices now engage in intraorganizational or extraorganizational teleradiology. In this era of patient primacy, optimizing patient care and care delivery is paramount. This article provides an update on recent changes, current challenges, and future opportunities centered around the ability of teleradiology to improve temporal and geographic imaging access. We review licensing and regulations and discuss teleradiology in providing services to rural areas and assisting with disaster response, including the response to the coronavirus disease (COVID-19) pandemic. CONCLUSION. Teleradiology can help increase imaging efficiency and mitigate both geographic and temporal discrepancies in imaging care. Technologic limitations and regulatory hurdles hinder the optimal practice of teleradiology, and future attention to these issues may help ensure broader patient access to high-quality imaging across the United States.

PURPOSE/OBJECTIVE:To demonstrate the generalizability of PRECISION findings and apply the PRECISION biopsy strategy to a contemporary cohort to characterize cancers missed by employing this strategy. MATERIALS AND METHODS/METHODS:629 men biopsied between 2/2015-9/2018 met PRECISION inclusion criteria. Men with PI-RADS 1-2 MRI were only biopsied if high clinical suspicion for cancer. Missed cancers were defined as prostate cancer (PCa) identified uniquely on systematic biopsy (SB) in men with PI-RADS 3-5 MRI, or on either SB or MRI-targeted prostate biopsy (MRI-TB) in men with PI-RADS 1-2 MRI. Outcomes included 1) clinically-significant PCa (csPCa), ≥Gleason grade group (GG) 2, detection rate (CDR), 2) missed csPCa rate upon application of PRECISION biopsy strategy, 3) GG distribution, core size, spatial orientation, and oncologic risk among missed cancers. RESULTS:Application of the PRECISION biopsy strategy to the study cohort resulted in avoidance of biopsy in 28%, similar MRI-TB CDR to PRECISION, reduction of GG1 CDR by 60%, and reduction of csPCa CDR by 19%. Missed csPCa were often <6 mm (54.5%), GG2 (67.3%), and low-risk by clinical nomogram (74.6%). GG1 cancers identified uniquely on SB were often contralateral to MRI target (46.4%), while missed csPCa was predominantly ipsilateral (81%). Limitations include biopsy of only men with high-risk clinical features among PIRADS 1-2 MRI, potentially overestimating the csPCa CDR. CONCLUSIONS:The study cohort demonstrated generalizability of PRECISION findings. Applying the PRECISION biopsy strategy greatly reduces GG1 CDR, while missing a small number of csPCa, typically small volume, low-risk, and GG2. Missed csPCa are predominantly ipsilateral to MRI target, possibly representing targeting error.

OBJECTIVE:Women are highly underrepresented among leadership positions within radiology research, disproportionate to their underrepresentation in radiology overall. We sought to identify the causes and solutions of such disparity at the personal, organizational, and institutional levels among female radiology researchers who are leaders in the field. SUBJECTS AND METHODS/METHODS:We used purposive sampling to identify nationally recognized female leaders in radiology research. We developed a semistructured interview guide and conducted in-depth one-on-one telephone interviews with participants (n = 16) that ranged from 36 to 65 min. All interviews were recorded and transcribed. Data were analyzed by two researchers trained in qualitative methods using Saldana's first- and second-cycle coding method. Themes were identified using a grounded theory approach to identify meaningful patterns that addressed the research question. RESULTS:Participants identified barriers to their professional development and success, including personal and professional obstacles often associated with work-life balance and the nonlinear nature of women's careers due to caregiving responsibilities. Participants also identified facilitators of success that operated at the individual, organizational, and institutional level, such as purposeful networking, having an advocate, and participating in leadership events. CONCLUSION/CONCLUSIONS:This study represents the first effort to qualitatively capture the facilitators of success for nationally recognized female radiology researchers. Findings suggest that synergistic efforts can be undertaken by early-career female radiologists and their colleagues, national radiology organizations, and academic institutions to systematically enable the inclusion and participation of women. The field of radiology should consider how to work dynamically at multiple levels to implement the identified potential changes.

OBJECTIVE:To characterize national trends in oncologic imaging (OI) utilization. METHODS:This retrospective cross-sectional study used 2004 and 2016 CMS 5% Carrier Claims Research Identifiable Files. Radiologist-performed, primary noninvasive diagnostic imaging examinations were identified from billed Current Procedural Terminology codes; CT, MRI, and PET/CT examinations were categorized as "advanced" imaging. OI examinations were identified from imaging claims' primary International Classification of Diseases-9 and International Classification of Diseases-10 codes. Imaging services were stratified by academic practice status and place of service. State-level correlations of oncologic advanced imaging utilization (examinations per 1,000 beneficiaries) with cancer prevalence and radiologist supply were assessed by Spearman correlation coefficient. RESULTS:The national Medicare sample included 5,030,955 diagnostic imaging examinations (1,218,144 of them advanced) in 2004 and 5,017,287 diagnostic imaging examinations (1,503,490 of them advanced) in 2016. In 2004 and 2016, OI represented 3.9% and 4.3%, respectively, of all imaging versus 10.8% and 9.5%, respectively, of advanced imaging. The percentage of advanced OI done in academic practices rose from 18.8% in 2004 to 34.1% in 2016, leaving 65.9% outside academia. In 2016, 58.0% of advanced OI was performed in the hospital outpatient setting and 23.9% in the physician office setting. In 2016, state-level oncologic advanced imaging utilization correlated with state-level radiologist supply (r = +0.489, P < .001) but not with state-level cancer prevalence (r = -0.139, P = .329). DISCUSSION/CONCLUSIONS:Oncologic imaging usage varied between practice settings. Although the percentage of advanced OI done in academic settings nearly doubled from 2004 to 2016, the majority remained in nonacademic practices. State-level oncologic advanced imaging utilization correlated with radiologist supply but not cancer prevalence.

PURPOSE/OBJECTIVE:To evaluate the effect of English proficiency on abdominal MRI imaging quality. METHODS:Three equal-sized cohorts of patients undergoing 3T abdominal MRI were identified based on English proficiency as documented in the EMR: Primary language of English; English as a second language (ESL)/no translator needed; or ESL, translator needed (42 patients per cohort for total study size of 126 patients). Three radiologists independently used a 1-5 Likert scale to assess respiratory motion and image quality on turbo spin-echo T2WI and post-contrast T1WI. Groups were compared using Kruskal-Wallis tests. RESULTS:For T2WI respiratory motion, all three readers scored the Translator group significantly worse than the English and ESL/no-Translator groups (mean scores across readers of 2.98 vs. 3.58 and 3.51; p values < 0.001-0.008). For T2WI overall image quality, all three readers also scored the Translator group significantly worse than the English and ESL/no-Translator groups (2.77 vs. 3.28 and 3.31; p values 0.002-0.005). For T1WI respiratory motion, mean scores were not significantly different between groups (English: 4.14, ESL/no-Translator: 4.02, Translator: 3.94; p values 0.398-0.597). For T1WI overall image quality, mean scores also were not significantly different (4.09, 3.99, and 3.95, respectively; p values 0.369-0.831). CONCLUSION/CONCLUSIONS:Abdominal MR examinations show significantly worse T2WI respiratory motion and overall image quality when requiring a translator, even compared with non-translator exams in non-English primary language patients. Strategies are warranted to improve coordination among MR technologists, translators, and non-English speaking patients undergoing abdominal MR, to ensure robust image quality in this vulnerable patient population.

RATIONALE AND OBJECTIVES/OBJECTIVE:To assess the prevalence and associated factors of burnout among U.S. academic radiologists. MATERIALS AND METHODS/METHODS:An online survey was sent to the radiologists who were full members of the Association of University Radiologists in December 2018. Burnout was measured using the abbreviated Maslach Burnout Inventory Human Services Survey. Survey respondents were also requested to complete questions on demographics, potential professional stressors, sense of calling, and career satisfaction. Associations between survey participants' characteristics and burnout were tested using logistic regression model. RESULTS:The survey response rate was 27% (228/831). Twenty-nine percent met all three criteria for high burnout, including high emotional exhaustion, high depersonalization, and low personal accomplishment. Seventy-nine percent had one or more symptoms of burnout. Numerous factors including work overload, inability to balance personal and professional life, lack of autonomy, lack of appreciation from patients and other medical staff were significantly associated (p < 0.05) with high burnout. Older age (OR, 0.95; 95%CI 0.92-0.98; p < 0.05), higher number of years of experience practicing as radiologists (OR, 0.95; 95%CI 0.92-0.98; p < 0.05), and holding academic rank of professor (OR, 0.25; 95%CI 0.11-0.56; p < 0.05) were factors associated with lower odds of experiencing burnout. Radiologists with high burnout were more likely to be dissatisfied with their career (OR, 2.28; 95%CI 1.70-3.07; p < 0.0001) and less likely to identify medicine as a calling. CONCLUSION/CONCLUSIONS:Multiple factors contribute to high burnout in academic radiologists. Familiarity with these factors may help academic radiology departments to develop strategies to promote health and wellness of their faculty.
