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.
