Magnetic resonance imaging (MRI) is a noninvasive procedure that uses radio waves and magnetic fields to produce images of body tissue. The images produced are more detailed than traditional x-ray images and computed tomography (CT) scans. The MRI is particularly important in identifying brain abnormalities that are small or only subtly different from normal tissue.
