Computed Tomography (CT) has recently gained in importance in the imaging of the heart. A basis for the use of CT is provided with articles on normal anatomy as well as anomalies, patient preparation and scanning techniques, and technology and radiation dose reduction strategies. Evaluation of plaques and stenosis, bypass grafts and stents, and myocardial abnormities and ischemia are reviewed. Acute chest pain and congenital heart disease are just two of the other topics included in this issue.
