The ABCs of MRI

Magnetic resonance imaging, or MRI, uses strong magnetic fields and radio waves to produce cross-sectional images of the body that are very detailed. These images are essential in detecting and diagnosing many medical conditions, and also in checking on how a patient's treatment is progressing. At FDA, medical physicists, computer engineers, and mathematicians help to make sure that MRI devices are safe and effective.
