CT Angiogram

Doctors use angiography to diagnose and treat blood vessel diseases and conditions. Angiography exams produce pictures of major blood vessels throughout the body. Most exams use contrast material.

Doctors perform angiography using:

• x-rays with catheters
• computed tomography (CT)
• magnetic resonance imaging (MRI)

CT angiography uses a CT scanner to produce detailed images of both blood vessels and tissues in various parts of the body. During the exam, contrast material is injected through a small catheter placed in a vein of the arm. A radiologic technologist will capture high-resolution CT images while the contrast material flows through the blood vessels

What are some common uses of the procedure?

CT angiography is helpful in examining blood vessels and the organs supplied by them in various body parts, including:

• brain
• neck
• heart
• chest
• abdomen (such as the kidneys and liver)
• pelvis
• legs and feet
• arms and hands
