We aimed to evaluate the ability of Rho, an artificial intelligence (AI) tool, to prospectively identify patients at-risk for low bone mineral density (BMD) from standard x-rays, its adoption rate by radiologists, and acceptance by primary care providers (PCPs).Methods: Patients ≥50 years were recruited when undergoing an x-ray of a Rho-eligible body part for any clinical indication. Questionnaires were completed at baseline and 6-month follow-up, and PCPs of \"Rho-Positive\" patients (those likely to have low BMD) were asked for feedback. Positive predictive value (PPV) was calculated in patients who returned within 6 months for a DXA.Results: Of 1145 patients consented, 987 had x-rays screened by Rho, and 655 were flagged as Rho-Positive. Radiologists included this finding in 524 (80%) of reports. Of all Rho-Positive patients, 125 had a DXA within 6 months; Rho had a 74% PPV for DXA T-Score <-1. From 51 PCP responses, 78% found Rho beneficial. Of 389 patients with follow-up questionnaire data, a greater proportion of Rho-Positive versus -negative patients had discussed bone health with their PCP since study start (36% vs 18%, P < .001), or were newly diagnosed with osteoporosis (11% vs 5%; P = .03).Conclusion: By identifying patients at-risk of low BMD, with acceptability of reporting by radiologists and generally positive feedback from PCPs, Rho has the potential to improve low screening rates for osteoporosis by leveraging existing x-ray data.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251380240"},"PeriodicalIF":3.7,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four anonymous online surveys were administered through Qualtrics to PGY 2-5 radiology residents from 2021 to 2025. These surveys identified residents with burnout and distress and assessed contributing factors, suggestions for reducing burnout, and residents' responses to implemented interventions. Interventions were employed at 2 hospitals within our institution.Results: The surveys had response rates of 30% (2021), 57.7% (2023), 60% (2024), and 62% (2025). 50% of pre-intervention respondents were identified as burned out. The rate reduced to 18.8% post-intervention, with results not being statistically significant (P = .167). Top factors driving burnout included time (eg, increased work hours, time constraints), extra duties (clinical and administrative), and perceived lack of radiology knowledge when dealing with complex cases. Interventions included additional daily 1-hour teaching sessions, wellness lunch rounds, debriefing sessions, transitioning from paper-based protocolling to a hybrid-electronic paper-based system, call schedule modifications, improved ergonomics, and social functions, including incorporating indoor and outdoor activities. Interventions targeting work hours were subjectively the most well-received in combating burnout.Conclusion: This study underscores the prevalence of burnout among radiology residents. Our institution has implemented a multi-faceted approach to address burnout within our radiology residency program.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251369842"},"PeriodicalIF":3.7,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145132846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inclusion criteria were HCC surveillance MRIs with either a full or abbreviated imaging protocol. Exclusion criteria were other abdominopelvic MR protocols or incomplete studies. DICOM time data were extracted via Quantivly and validated with 10 prospective time studies. Exam times from PACS images were cross-referenced with DICOM data to identify and resolve extraction outliers. Power logs from 10 exams per protocol were used to quantify energy and greenhouse gas emissions. Schedule logs assessed appointment volume changes. Mean times (±SD) and energy (±SD) were reported, and Welch's t-test determined statistical significance (P < .05).Results: Exam times for 487 MRIs (318 abbreviated, 169 full protocol) were analyzed, with 67 excluded. The mean duration of exam time for the abbreviated protocol was 12.0 minutes (SD: 4.3), compared with 29.7 minutes (SD: 8.8) for the full protocol (mean difference, 17.7 minutes; P < .0001). The mean energy for the abbreviated protocol was 4.7 kWh (SD: 0.6), compared with 11.7 kWh (SD: 1.3) for the full protocol (mean difference, 7.0 kWh; P < .0001). Across 318 abbreviated exams, estimated savings totaled 2226 kWh and 1494.6 kg CO2eq. Despite time savings, MRI appointment volume and scanner access remained unchanged.Conclusion: Abbreviated HCC surveillance MRIs cut scan time, energy use, and carbon emissions by 60%, but scheduling complexities precluded increased MRI appointments.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251371567"},"PeriodicalIF":3.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145076623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective was to assess whether prostate cancer segmentation models trained on local MRI data continue to outperform those trained on external data with cohorts exceeding 1000.Methods: We simulated a multi-institutional consortium using the public PICAI dataset (PICAI-TRAIN: 1241 exams, PICAI-TEST: 259) and a local dataset (LOCAL-TRAIN: 1400 exams, LOCAL-TEST: 308). IRB approval was obtained and consent waived. We compared nnUNet-v2 models trained on the combined data (CENTRAL-TRAIN) and separately on PICAI-TRAIN and LOCAL-TRAIN. Accuracy was evaluated using the open source PICAI Score on LOCAL-TEST. Significance was tested using bootstrapping.Results: Just 22% (309/1400) of LOCAL-TRAIN exams would be sufficient to match the performance of a model trained on PICAI-TRAIN. The CENTRAL-TRAIN performance was similar to LOCAL-TRAIN performance, with PICAI Scores [95% CI] of 65 [58-71] and 66 [60-72], respectively. Both of these models exceeded the model trained on PICAI-TRAIN alone which had a score of 58 [51-64] (P < .002). Reducing training set size did not alter these relative trends.Conclusion: Domain shift limits MRI prostate cancer segmentation performance even when training with over 1000 exams from 3 external institutions. Use of local data is paramount at these scales.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251367620"},"PeriodicalIF":3.7,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145041919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey garnered 129 complete responses, for a response rate of 6.6%.Results: Respondents predominantly practiced in academic settings (65.9%) and had subspecialty training (96.1%). The majority reported that MDT rounds lasted 30 to 60 minutes and discussed 6 to 10 cases. Most radiologists (62.8%) were the sole presenters of imaging. Preparation time was often limited, with only 6.2% having dedicated time for preparation. 59.8% of respondents reported receiving additions to caseloads within the 24-hour period prior to the meetings. While 93.8% valued the opportunity for interaction with colleagues, 93.8% felt inadequately compensated for their efforts by their practices, while 92.3% felt inadequately compensated by their province.Conclusions: While most radiologists indicated adequate time for discussion and meaningful clinical engagement during rounds, many highlighted repeated challenges such as last-minute case additions, lack of protected preparation time, and technological barriers. Systemic barriers also play a role and include lack of provincial remuneration and workforce issues which in turn impact individual workload pressures.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251365205"},"PeriodicalIF":3.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144979266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
