During an MRA scan, you lie on a cushioned table that moves into the scanner. An injected contrast agent may be used to make blood vessels more visible on your images. These contrast agents rarely cause allergic reactions.

Magnetic Resonance Angiography (MRA) is a magnetic resonance imaging (MRI) study that is obtained with the same scanning machine. An MRA exam uses a strong magnetic field combined with radiofrequency waves to create highly detailed images of blood vessels in the body. This scan is often used to help identify abnormalities or diagnose atherosclerotic (plaque) disease. During an MRA scan, you lie on a cushioned table that moves into the scanner. An injected contrast agent may be used to make blood vessels more visible on your images.
