Magnetic Resonance Imaging (MRI) of the Knee

What To Think About

  • You may be able to have an MRI with an open MRI machine camera.gif that doesn't enclose your entire body. But open MRI machines aren't available everywhere. The pictures from an open MRI may not be as good as those from a standard MRI machine camera.gif.
  • Sometimes your MRI test results may be different than those from CT, ultrasound, or X-ray tests because the MRI scan is more specific.
  • In some people, a knee MRI has given enough information about the knee joint that those people do not need an arthroscopy. To learn more, see the topic Arthroscopy.
  • Contrast material put directly in the knee (arthrogram) may be done in people who can't have an MRI or where MRI is not available. An arthrogram may also be done in people with total knee joint replacements to check for loose parts. To learn more, see the topic Arthrogram.
