Point/counterpoint: dose-related issues in cardiac CT imaging

Authors: Beverley Newman, Shreyas S. Vasanawala

Published in: Pediatric Radiology | Special Issue 2/2011

Abstract

This manuscript reviews some of the more controversial dose-related issues in cardiac CT imaging. Discussion covers the relative merits of cardiac CT versus MR, advantages and concerns regarding gated versus nongated cardiac CT and advantages and concerns regarding the use of breast shields in girls undergoing cardiac CT imaging.
