A traditional CT scan is an x-ray procedure that combines many x-ray images with the aid of a computer to generate cross-sectional views of the body. Cardiac CT uses the advanced CT technology with intravenous (IV) contrast (dye) to visualize your cardiac anatomy, coronary circulation and great vessels. Cleveland Clinic uses state-of-the-art multi-row detector CT scanners. With multi-slice scanning, it is possible to acquire high-resolution three-dimensional images of the moving heart and great vessels.
A cardiac computed tomography also may be called a coronary CT angiography, MSCT, CT, cardiac CT, coronary CTA or cardiac CAT scan.
Cardiac CTs are used to evaluate:
- The heart muscle
- The coronary arteries
- The pulmonary veins
- The thoracic and abdominal aorta
- The sac around the heart (pericardium)
