Canadian Computed Tomography Survey : national diagnostic reference levels / [prepared by Graeme M. Wardlaw and Narine Martel].: H129-61/2016E-PDF
This report summarizes the results of the first Canadian Computed Tomography (CT) Survey and provides national Diagnostic Reference Levels (DRLs) for CT imaging in Canada. CT is a valuable x-ray imaging tool in medicine, providing information that supports the diagnosis, treatment, and monitoring of patients. While the clinical applications of CT equipment and their benefits to patients are significant, there is increased global focus on the need to carefully manage radiation exposures from CT imaging, as radiation doses from CT examinations are in general, higher than those from most other medical x-ray imaging examinations. An internationally recognized approach to radiation protection of patients, recommended by the International Commission on Radiological Protection (ICRP), is the establishment and use of DRLs. DRLs are dosimetric indicators, established from surveys of imaging practice and provide guidance to help manage dose and promote optimization, so that the applied dose is appropriate for a given clinical need. The primary goal of the Canadian CT Survey was to collect CT dose index data in order to establish national DRLs for commonly performed CT examinations of adults and pediatric patients. The survey was conducted using a highly collaborative approach between Health Canada, provincial and territorial governments as well as medical associations and other healthcare professionals who helped shape the survey, and promoted survey participation. The National CT Survey provides a current snap-shot of CT equipment technology and CT imaging practices in Canada. The national DRLs will help promote optimization of CT clinical protocols in Canada and ultimately contribute to national and international efforts to minimize medical exposures to ionizing radiation from CT.
