It is one of the most advanced CT Scans available for non - invasively imaging the Coronary Arteries (CT Coronary Angiogram). It can image the entire heart in 3 heart beats. The Radiation doses are extremely low, comparable to the standard Cath lab Angiogram or even less. It is also useful in evaluating the status of the stent placed in Coronary arteries and grafts placed during by-pass surgery. This scan has the most advanced technique to reduce the radiation doses and is very fast. The volume of contrast ( dye ) injected is less than that required by other machines.
