An Environmental Scan of the National and Provincial Diagnostic Reference Levels in Canada for Common Adult Computed Tomography Scans.

Can Assoc Radiol J 2019 Feb 13. Epub 2019 Feb 13.

Department of Radiology, McMaster University, Hamilton, Ontario, Canada.

Several regulatory bodies have agreed that low-dose radiation used in medical imaging is a weak carcinogen that follows a linear, non-threshold model of cancer risk. While avoiding radiation is the best course of action to mitigate risk, computed tomography (CT) scans are often critical for diagnosis. In addition to the as low as reasonably achievable principle, a more concrete method of dose reduction for common CT imaging exams is the use of a diagnostic reference level (DRL). Read More

Interobserver Variation of Colonic Polyp Measurement at Computed Tomography Colonography.

Can Assoc Radiol J 2019 Feb;70(1):44-51

Department of Diagnostic and Interventional Radiology, Royal Perth Hospital, Perth, Western Australia.

Background: The concept of "advanced polyps" is well accepted and is defined as polyps ≥10 mm and/or those having a villous component and/or demonstrating areas of dysplasia. Of these parameters, computed tomography colonography (CTC) can only document size. The accepted management of CTC-detected "advanced polyps" is to recommend excision if feasible, whereas the management of "intermediate" (6-9 mm) polyps is more controversial, and interval surveillance may be acceptable.

Gadolinium Deposition in the Brain: A Systematic Review of Existing Guidelines and Policy Statement Issued by the Canadian Association of Radiologists.

Can Assoc Radiol J 2018 Nov 22;69(4):373-382. Epub 2018 Sep 22.

Department of Radiology, The Ottawa Hospital, University of Ottawa, Ottawa, Ontario, Canada. Electronic address:

Emerging evidence has confirmed that, following administration of a gadolinium-based contrast agent (GBCA), very small amounts of gadolinium will deposit in the brain of humans with intact blood-brain barriers. The literature is evolving rapidly and the degree to which gadolinium will deposit for a particular GBCA or class of GBCAs remains undetermined. Several studies suggest that linear GBCAs deposit more gadolinium in the brain compared with macrocyclic GBCAs; however, our understanding of the molecular composition of deposited gadolinium is preliminary, and the clinical significance of gadolinium deposition remains unknown.

Management of Acute Contrast Reactions-Understanding Radiologists' Preparedness and the Efficacy of Simulation-Based Training in Canada.

Can Assoc Radiol J 2018 Nov 20;69(4):349-355. Epub 2018 Sep 20.

Department of Radiology, Vancouver General Hospital, Vancouver, British Columbia, Canada.

Purpose: Acute radiologic emergencies, primarily severe contrast reactions, are rare but life-threatening events. Given a generalized paucity of formalized or mandated training, studies have shown that radiologists and trainees perform poorly when acutely managing such events. Moreover, skill base, knowledge, and comfort levels precipitously decline over time given the infrequent occurrence of these events during one's daily practice. Read More
