Types of X-rays and Scans. MRA (Magnetic Resonance Angiography) MRAâa type of magnetic resonance imaging (MRI) study that is obtained with the same scanning machineâuses a strong magnetic field combined with radiofrequency waves to create highly detailed images of blood vessels in the body. (MRA is most often used to examine vessels in the brain, neck, kidneys, and legs.) The resulting scans, which provide information about blood flow and the condition of blood vessel walls, may then be saved on a computer or on film and examined for abnormalities.
