Abstract
Since the introduction of Multi Detector Row CT(MDCT)in 1998, technology in cardiac imaging has advanced continuously up to today. Clinical utility of Cardiac CT was first recognized with 16ch MDCT introduced in 2001, and with the emergence of 64ch MDCT in 2004, the clinical utility seems to be well established. In just 6 years, Cardiac CT has gone through series of technology advancement from scanning to image processing in a very short period of time. Today, the speed of technology evolution shows no sign of slowing down. SnapShot Pulse is a new technology in cardiac scan that can reduce X-ray dose so inherent with conventional retrospective gating helical scan technology. SnapShot Pulse is step-&-shoot scanning technology with prospective gating and can reduce X-ray dose up to 87.5%.
