Angiogram of the Head and Neck

Test Overview

An angiogram of the head and neck is an X-ray, Opens dialog test that uses a special dye and camera (fluoroscopy, Opens dialog) to take pictures of the blood flow in the blood vessels of the head and neck, Opens dialog. An angiogram of the neck (carotid angiogram) can be used to look at the large arteries in the neck that lead to the brain. An angiogram of the head (cerebral angiogram) can be used to look at the veins or the four arteries (four-vessel study) carrying blood to the brain.

During an angiogram, a thin, soft tube called a catheter is placed into a blood vessel in the groin or just above the elbow. The catheter is guided to the head and neck area. Then an iodine dye (contrast material, Opens dialog) is injected into the vessel to make the area show clearly on the X-ray pictures. The angiogram pictures can be made into regular X-ray films or stored as digital pictures in a computer.

An angiogram can find a bulge in a blood vessel (aneurysm, Opens dialog). It can also show narrowing or a blockage in a blood vessel that slows or stops blood flow. An abnormal pattern of blood vessels (arteriovenous [AV] malformation) or abnormal vessels near a tumor can be seen.

A magnetic resonance angiogram, Opens dialog (MRA) or computed tomography angiogram, Opens dialog (CTA) may be an option instead of a standard angiogram. Each of these tests is less invasive than an angiogram. Some MRA tests and all CTA tests require an injection of dye. A CTA also involves radiation exposure.
