A significant advantage of a CT angiogram over a traditional angiogram is that a CT angiogram is non-invasive. However, for cases of abnormal CT angiogram results - such as one or several blood vessels being blocked or narrowed - a standard angiogram may be required as a follow-up. This is...

contrast fluid via an IV, and usually a 64-slice scanner creates a detailed three-dimensional image of the beating heart that a doctor can examine for evidence of fatty or calcium deposits. This test is less invasive and less expensive, but somewhat less accurate, than the standard angiogram....
