Multidetector row CT scanners with submillimeter spatial resolution and high temporal resolution are now available and are increasingly used for noninvasive assessment of vascular disease including coronary arteries and grafts. The entire heart and graft course can be scanned within a single breath-hold, and contrast-enhanced images are reconstructed through retrospective ECG gating. In this pictorial review, we describe the CT findings of the most commonly used coronary artery bypass grafts on both axial images and two-dimensional and three-dimensional images providing a correlation with conventional coronary angiography.
Key Words: coronary artery bypass graft coronary artery disease multidetector row CT
