Justin E Costello et al. AJR Am J Roentgenol. 2013 Dec.

Abstract

Objective: The purpose of this article is to use clinical scenarios to explore aspects of ionizing radiation imparted to patients undergoing CT examinations. Examination appropriateness, effective doses, cancer risks, and pertinent dose reduction strategies are reviewed.
