A CT angiogram is a way of looking at the blood vessels in different parts of your body.
A small cannula is placed in a vein in your arm and then IV contrast is injected at a fast rate while you are in the CT scanner. The scanner will image the part of your body that your doctor wants assessed. The CT scanner can reconstruct the images in 3D to give a really good picture of the vessels and show problems like narrowing and aneurysms.
A cannula will be placed in your arm before the scan. You will be positioned on your back with your arms above your head. During the injection of IV contrast your abdomen will pass through the scanner as the images are acquired.
