This procedure images the blood vessels supplying the neck and brain by threading a thin tube (catheter) through the blood vessels up to the main artery in the chest, then injecting contrast dye while taking a series of x-ray images. It provides a detailed map of blood flow through the carotid and vertebral arteries and the vessels inside the skull. It's used to look for narrowing, blockages, aneurysms, or other blood vessel abnormalities before deciding on treatment.
