What it means
An MRA uses magnetic resonance imaging technology to produce detailed pictures of blood vessels throughout the body without using X-ray radiation. It is particularly useful for examining the arteries in the brain, neck, kidneys, and legs. You will lie still inside a large tube-shaped MRI machine. Some MRA exams use an intravenous contrast dye called gadolinium to make vessels more visible; others do not require any contrast at all. The machine makes loud knocking sounds during the scan, and you will be given earplugs. The exam takes 30 to 90 minutes. You must remove all metal objects and inform staff of any implants. People with kidney disease should inform the doctor before gadolinium contrast is used.
