In brief: MRI vs. CT

A ct (or cat) scan uses xrays and special computers to image the body.
An MRI uses a combination of strong and weak magnets, radiofrequency coils and special computers to create images. There are certain body parts and disease processes that are better visualized with ct vs. Mri. Your doctor and/or the radiologist decide which test to perform based on many factors.
