What is coronary computed tomography angiogram or CTA? A coronary computed tomography angiogram (CTA) uses advanced CT technology, along with intravenous (IV) contrast material (dye), to obtain high-resolution, 3D pictures of the moving heart and great vessels. CTA is also called multi-slice computed tomography (MSCT), cardiac CT or cardiac CAT. During CTA, x-rays pass through the body and are picked up by detectors in the scanner, that produce 3D images on a computer screen.
