MR angiography uses a powerful magnetic field, radio waves, and a computer to evaluate blood vessels and help identify abnormalities. It diagnosed atherosclerotic disease for millions of patients last year alone. These exams do not use ionizing radiation and likely require an injection of a contract material called gadolinium, a substance much less likely to cause an allergic reaction than iodinated contrast material. With this change, more patients enjoy a comfortable and stress-free exam and are done far faster than traditional methods.
Tell the Doctor

In regard to clothing, you may be asked to wear a hospital gown.
Claustrophobia

You must remain as still as possible during the exam. If you worry that you may not handle the stress of this well, ask your doctor about a mild sedative before the procedure to allow greater peace of mind.
In short, you receive a simple shot of dye in the arm, a few minutes on a sliding table, and then you can return to your room or home.
