Canadian radiology: 2026 update.

Abstract

Canadian radiology continues to produce scholarship that is technically sophisticated, clinically relevant, and increasingly attentive to the wider systems in which imaging is delivered. The purpose of this article was to provide an update on selected work shaping radiology in Canada across major subspecialties and domains of practice. In abdominal radiology, notable developments include oncologic imaging research, disease-specific guidance, referral recommendations, and updated approaches to contrast media hypersensitivity. Canadian researchers have made significant contributions to cardiothoracic radiology, including works in cardiac magnetic resonance imaging, opportunistic cardiovascular risk assessment, low-dose imaging techniques, artificial intelligence evaluation, climate-related imaging research, and consensus guidance. Canadian interventional radiology continues to demonstrate strong international influence through major clinical trials, translational device development, and scholarship addressing access and environmental sustainability. In musculoskeletal radiology, recent work has focused on fracture risk assessment, imaging utilization in acute sports injury, and evidence-based referral pathways. In neuroradiology, Canadian centers remain highly influential in acute ischemic stroke imaging and intervention, imaging for brain-based death determination and prognostication in critically ill patients, and the emerging role of middle meningeal artery embolization for chronic subdural hematoma. Collectively, these contributions reflect a field marked by methodological rigor, clinical relevance, and a strong commitment to translating evidence into practice.
