What is an angiogram? 

Often referred to as a "diagnostic" or "catheter cerebral" angiogram, this is a test that evaluates blood vessels (arteries and veins) in your head and neck by taking pictures of blood flow through the vessels. To produce the pictures, a dye is injected into the vessels via a small tube called a catheter. The dye allows us to see the pattern of blood flow in the brain.
