CT Coronary Angiogram
An imaging test that looks at the arteries that supply blood to your heart. It might be used to diagnose the cause of chest pain or other symptoms. A CT coronary angiogram relies on a powerful X-ray machine to produce images of your heart and its blood vessels. A coronary CT angiogram can check your heart for various conditions, but it’s primarily used to check for narrowed or blocked arteries in your heart (coronary artery disease).
An intravenous (IV) line will be inserted in to your hand or arm to inject the dye that will make your heart’s arteries visible on the images.
Electrodes will be placed on your chest to record your heart rate. You’ll lie on a long table that slides through a short, tunnel-like machine. During the scan you’ll need to stay still and hold your breath so as not to blur the images. If you’re uncomfortable in closed spaces, you may request medication to help you relax.
