A CT angiogram scan, also known as CTA, focuses on your blood vessels. By injecting a contrast dye that shows up brightly on the CT scan, it creates detailed images of your arteries and veins throughout your body. This allows doctors to see blockages, narrowings (stenosis), aneurysms (bulges), or other abnormalities within your vascular system. This information is crucial for diagnosing conditions like coronary artery disease (affecting heart arteries), peripheral artery disease (affecting leg arteries), and blood clots.

An angiogram CT scan, also known as CT angiography (CTA), combines a regular CT scan with an injection of contrast dye. This special dye highlights your blood vessels in the resulting images. Think of it as a CT scan with a built-in highlighter for your blood vessels. This allows doctors to see blockages, narrowing, or other abnormalities in your arteries and veins throughout your body. It’s a valuable tool for diagnosing heart disease, peripheral artery disease, and other vascular conditions.
