Journal of Computer Assisted Tomography: July/August 2004 - Volume 28 - Issue - p S46-S49 doi: 10.1097/01.rct.0000120856.80935.f4 Buy Metrics Abstract A substantial increase in computed tomography (CT) scanning with availability of state-of-the-art multidetector-row CT scanners has generated debate about its safety and considerable interest in formulating clinical and technologic strategies to reduce radiation exposure. This review describes the magnitude of radiation exposure associated with CT scanning and projected radiation risks as well as clinical strategies and major technologic innovations for reducing radiation dose to patients undergoing CT scanning. © 2004 Lippincott Williams & Wilkins, Inc.
