Principles and Pitfalls in Cardiac Imaging

Multidetector row computed tomography (MDCT) is becoming one of the most rapidly growing radiologi-cal techniques since the introduction of computed tomography. The advantages of faster gantry rotation speed and sophisticated algorithms allow for data re-construction from various cardiac phases. Most pit-falls can be overcome through appropriate image data reconstruction. Multidetector CT scanners with >4 detector rows will result in improved temporal and spatial resolution and fewer motion artifacts. This new technology allows for cardiac imaging. The focus of this article will be on the basic principles and techniques as well as some of the common pitfalls of MDCT coronary angiography.
