Interest in MMA embolization is rapidly accelerating across both public and academic domains. journals.sagepub.com/doi/abs/10.117…

This study aimed to evaluate the ability of Rho, an 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). journals.sagepub.com/doi/full/10.11…

Burnout rates are high among radiology residents. Top factors driving burnout include time, extra duties, and perceived lack of knowledge. A multi-faceted approach in burnout interventions was applied within a large Canadian residency program. bit.ly/3PiNZIw

Abbreviated HCC surveillance MRIs cut scan time, energy use, and carbon emissions by 60%, but scheduling complexities precluded increased MRI appointments. journals.sagepub.com/doi/full/10.11…

Domain shift continues to be a problem for deep learning MRI prostate cancer segmentation models even when trained on over 1000 exams spanning three institutions. Incorporation of local data remains critical for optimal performance. journals.sagepub.com/doi/full/10.11…

Selon une enquête nationale mesurant les perceptions des gardes des résidents, ce sont quelques-unes des expériences les plus couramment citées par les résidents en radiologie de garde. car.ca/fr/nouvelles/e…

High call volumes and limited rest. Challenging interactions with referring physicians. According to a national survey measuring the perceptions of resident call, these are some of the most common cited experiences of radiology residents on call. car.ca/news/examining…

Canadian radiologists value MDT rounds for collaboration but face significant challenges. 93.8% feel undercompensated, 60% deal with last-minute cases, and only 6.2% have dedicated prep time. journals.sagepub.com/doi/full/10.11…

MRI-guided prostate biopsies show 59% accuracy in detecting significant cancer. Higher success rates (74%) seen with PI-RADS 5 scores, elevated PSA density & ultrasound-visible lesions. Small lesions (<7mm) less likely to be cancer. journals.sagepub.com/doi/full/10.11…

A study of 421 parathyroid scans shows higher calcium levels strongly predict positive results. Findings suggest need for tailored biochemical criteria between primary & secondary hyperparathyroidism. journals.sagepub.com/doi/full/10.11…

Deep Learning-accelerated MRI matches or outperforms traditional pelvic scans while cutting scan time. Research shows superior image quality in most cases, better contrast ratio, and reduced artifacts. journals.sagepub.com/doi/full/10.11…

New strategies aim to boost patient throughput despite limited resources, while calling for provincial & national policies to build sustainable radiology services for the future. journals.sagepub.com/doi/full/10.11…

Dual-energy CT is transforming pancreatic imaging: enhancing contrast, reducing artifacts, and optimizing radiation dose. This review highlights its impact across tumor detection, trauma, and pancreatitis care. journals.sagepub.com/doi/full/10.11…

CTA overestimates MCA M1 vessel diameter compared to DSA in stroke patients undergoing EVT. This modest discrepancy could impact device choice in borderline cases - radiologists should be aware. journals.sagepub.com/doi/full/10.11…

Checkpoint inhibitors have transformed cancer care but assessing response is tricky. Pseudo-progression can mislead traditional RECIST criteria. This review demystifies iRECIST, offering tools to better evaluate immunotherapy outcomes. journals.sagepub.com/doi/full/10.11…

AI, sustainability, and efficiency took center stage in radiology in 2025. The CARJ “Year in Review” highlights 10 impactful articles shaping the future of the field—and our planet. How do we evolve with AI while reducing our footprint? journals.sagepub.com/doi/abs/10.117…

Interventional neuro-oncology is reshaping cancer care with minimally invasive, image-guided techniques for brain, spine, and head-neck tumors. From embolization to targeted drug delivery, this evolving field is pushing boundaries. journals.sagepub.com/doi/abs/10.117…

New CT-based score improves prediction of overall survival in adrenocortical carcinoma. By combining tumor shape, size, and ENSAT stage, it outperforms ENSAT alone in stratifying patient prognosis. journals.sagepub.com/doi/abs/10.117…

The reporting of O-RADS risk category increased from <5% to 88% over a 16-month period with a high level of agreement among readers in assigning O-RADS risk category. journals.sagepub.com/doi/full/10.11…
