Cardiac computed tomography angiogram (CCTA) uses advanced CT technology, along with intravenous contrast material (dye), to obtain high-resolution, 3D pictures of the moving heart and great vessels.
Through a CCTA a physician can see blockages and areas of narrowing in a patient's heart arteries on the images. Physicians can use the test to help detect or evaluate:
- Coronary heart disease
- Calcium buildup in the walls of the coronary arteries
- Problems with the aorta including aneurysms and dissection
- A pulmonary embolism
- Problems in the pulmonary veins
- Problems with heart function and heart valves
- Periocardial disease
- Results of coronary artery bypass grafting
