CTA stands for coronary computed tomography angiogram. A CT angiogram takes pictures of the heart. The pictures are more detailed than a typical x-ray. During a CT angiogram pictures are taken of cross sections or slices of the heart. When contrast is used during a CT scan pictures of the heart are highlighted even more. Ct scans can help determine a diagnosis early. Your doctor will use this information to determine the best treatment for you.
