Multidetector computed tomography (MDCT) allows for evaluation of native coronary arteries, coronary artery anomalies, bypass graft patency and quantification of atherosclerosis. Multidetector CT provides a safe, accurate, noninvasive alternative to invasive coronary angiograms in a select patient population. Successful CTA acquisition involves various components that this article will focus on, including adequate patient preparation, utilization of beta-blockers for heart rate control, understanding the principles of scan acquisition, and optimization of radiation dose. The current limitations of CTA and the potential role of dual-source CT (DSCT) to resolve many of the current limitations are also discussed. [ABSTRACT FROM AUTHOR] |
