Executive Summary

Diagnostic reference levels (DRLs) are used in medical imaging to indicate whether the patient radiation dose or amount of administered activity from a specific procedure are unusually high or low for that procedure. DRLs are the first step in the optimization process to manage patient dose commensurate with the medical purpose of the procedure. Achievable dose is an optimization goal, based on survey data, and typically defined as the median value (50th percentile) of the dose distribution of standard techniques and technologies in widespread use. The overarching goal is to obtain image quality consistent with the clinical objective, while avoiding unnecessary radiation. Too low an exposure, however, is also to be avoided if it results in an inadequate image.
