Coronary computed tomography angiography (CTA), sometimes referred to as coronary CT angiography, is a new procedure used to diagnose coronary artery disease. Studies are performed on a state-of-the-art 64-channel GE VCT-XT scanner (which takes 64 pictures a minute of the coronary arteries) along with contrast material given through an IV to produce high-resolution, 3D images of the moving heart and vessels. Coronary angiography is a noninvasive method for detecting blockages in the coronary arteries and can be performed much faster than a cardiac catheterization with less risk, discomfort and decreased recovery time.
Not all patients are candidates for a coronary angiography. You should meet the usual requirements for contrast-enhanced CT. If you have an allergy or have had a reaction to contrast material, you may not be a candidate for coronary CT angiography. Additionally, a regular heart rhythm and rate (below 65bpm) are generally required. Your primary care physician will help determine whether coronary CT angiography is right for you.
As soon as the procedure is complete, you can resume your regular activities. Our radiologists will review your test results and will send them to your doctor to discuss the results and any next steps with you.
