Cardiac CT obtains information about coronary arteries, great arteries and veins, and heart valves. It shows the location and extent of calcified plaque in the coronary arteries and helps detect coronary artery disease at an early stage, which neither traditional imaging techniques nor cardiac testing can do. Over the last decade technologic advances in CT angiography have been made at a rapid rate, and the new applications and refinements of existing technology continue to be made. This issue will help practicing cardiologists to keep up with the latest technology in this important and swiftly moving field.
