A secondary outcome is to determine potential barriers to the provision of IR after-hours on call services within the province. Methods: A survey was created and distributed to the radiology department heads across Ontario during a 6-week period in 2024. Results: The survey was sent to the department heads at 73 hospitals across the province of Ontario. Survey completion rate was 41% (30/73). Two thirds of the respondents had formal IR divisions (20/30, 66.7%). A total of 14 hospitals with IR departments offered on call services (70%, 14/20) and 2 of the hospitals without IR departments (2/10, 20%) offered on call services for non-vascular IR procedures (eg, abscess drainage). 92.9% of the groups offering IR call services stated year-over-year demand was increasing. The most common barrier to after-hours services were staffing resources. Conclusion: After-hours IR services have limited availability in the province of Ontario, and not all hospitals with IR departments currently provide after-hours access to IR procedures. The main barrier to provision of after-hours services is the lack of health human resources, in particular IR physicians.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251340368"},"PeriodicalIF":2.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144152873","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}

Multiparametric MRI (mpMRI) is currently the gold standard for PCa detection, diagnosis, and active surveillance. However, its reliance on dynamic contrast-enhanced (DCE) imaging introduces safety concerns, higher costs, and longer scan times. Biparametric MRI (bpMRI), which omits DCE, has emerged as a streamlined alternative that retains T2-weighted and diffusion-weighted imaging. This review critically examines the technical considerations, diagnostic performance, clinical applications, and limitations of bpMRI compared to mpMRI. We evaluate bpMRI's sensitivity, specificity, and negative predictive value in detecting clinically significant prostate cancer (csPCa), highlighting its advantages in terms of patient safety, accessibility, and cost-effectiveness. Despite promising findings, the widespread clinical adoption of bpMRI is hindered by variability in imaging protocols, limited large-scale validation, and concerns over missed subtle lesions. Future directions include standardizing bpMRI protocols, integrating artificial intelligence and biomarkers, and conducting multi-centre trials to establish its role in PCa management. bpMRI holds significant potential as a reliable and efficient imaging tool that could complement or replace mpMRI in select clinical contexts.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251342706"},"PeriodicalIF":2.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144152876","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}

Methods: A Steering Committee comprising multidisciplinary MSK experts was convened to guide recommendation development. Using a two-round Delphi method, committee members selected the top 3 scenarios from the CAR MSK referral guidelines deemed most impactful for addressing overuse. Recommendations based on these scenarios were then drafted using the CWC format. Results: The 3 recommendations developed are: (1) Don't order MRI without first considering ultrasound for the assessment of rotator cuff pathology and bursitis; (2) Don't order MRI of the hip or knee when x-ray demonstrates greater than mild osteoarthritis, unless recommended by a musculoskeletal specialist; and (3) Don't order MRI of the hip just based on x-ray features of femoroacetabular impingement unless there are clinical signs and symptoms of joint impingement. Conclusions: This project represents a knowledge translation initiative to disseminate updated MSK imaging guideline recommendations. It strengthens the collaboration between CAR and CWC and establishes a reproducible structured consensus approach that can be applied to developing additional CWC imaging recommendations across the remaining 12 CAR referral guidelines in other subspecialties. This work supports value-based radiology, promoting optimized resource use.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251339389"},"PeriodicalIF":2.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144152888","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}

However, CTA overutilization has been reported in some centres, and improper use has been linked to increased healthcare costs and prolonged Emergency Department wait times. This study evaluated CTA utilization in a Canadian Level I trauma centre, determined the rate of positive CTA studies requiring intervention, and identified factors that may reduce unnecessary examinations. Methods and Materials: This retrospective study included trauma patients who underwent lower extremity CTA between January 2020 and September 2024. Data regarding patient demographics, mechanism of injury, physical exam and computed tomography findings, ankle-brachial index value, and interventions were collected and evaluated. Statistical analysis included descriptive statistics and chi-square or Fisher's exact tests for categorical associations. Results: Six hundred twelve patients (82% male, median age 32 years) were included. Forty-six percent had a normal physical exam, and CTA was positive in 27% of cases. Eight percent of patients required an intervention, all of whom had at least one hard sign of vascular injury. A statistically significant association was identified between hard signs of a vascular injury and positive CTA findings (P < .001) and major vascular injuries (P < .01). No patients with a normal physical exam and a positive CTA required intervention. Conclusion: Nearly half of the CTA studies were performed on patients with a normal physical exam, none requiring intervention. Our findings suggest that implementing institution-specific appropriate criteria may reduce unnecessary CTA studies.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251342064"},"PeriodicalIF":2.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144152879","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}

Quality Initiative/Improvement (QI) projects lead to improved patient care and safety as well as efficient use of limited health care resources. When designing a QI project, including an environmental lens increases awareness of sustainability in medicine. This document will focus specifically on sustainability in QI (SusQI) in the field of Radiology, though similar principles may be applied in other medical fields. The sustainable QI model updates the value equation denominator from cost to the triple bottom line of environmental, social, and economic measures. Using this SusQI model can lead to a win (patient)-win (health care system)-win (environment). This article will also discuss the importance of the environment for human health and the link between quality initiatives and environmental sustainability in demonstrating the value of radiology and improving the quality of patient care. It will provide some examples of sustainability applied to many quality initiatives in radiology: For example, reduction in oral contrast use for many previously used indications, streamlined MRI protocols, as well as using ultrasound over CT or MRI for indications that are equally appropriate.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251340243"},"PeriodicalIF":2.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144152891","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}

Rooted in nuclear medicine, this approach uses molecular targeting agents labelled with diagnostic radioisotopes for imaging and therapeutic radioisotopes for treatment, ensuring a seamless transition from diagnosis to therapy. The field has evolved significantly in the last decade, with prostate-specific membrane antigen (PSMA)-targeted radioligand therapy transforming prostate cancer patient management and somatostatin receptor (SSTR)-targeted agents revolutionizing neuroendocrine tumour (NET) treatment. Considering its interdisciplinary nature, collaboration between nuclear medicine specialists, oncologists, radiologists, and other healthcare professionals is critical to refining clinical applications and improving patient outcomes. As prominent members of the theranostic team, radiologists play a pivotal role, from patient selection and imaging-based eligibility assessment to response evaluation and long-term monitoring. In this regard, advanced imaging modalities facilitate the precise evaluation of disease characteristics, guiding treatment decisions. Hence, as theranostics becomes increasingly integrated into patient management, radiologists face the need to be well-versed in both the technical aspects and clinical implications. In this review, we aimed to provide a primer for radiologists to gain a general insight into the theranostic field and its basic principles.","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251338032"},"PeriodicalIF":2.9,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144129645","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}
