What is it?

A CT coronary angiogram is the use of a CAT scan to non-invasively obtain images of your coronary arteries to exclude significant narrowings.

During the test, iodine contrast or dye is injected from the arm veins to opacify the arteries, during which time the X-ray images will be taken.
