Knee MRI - Overview & Technique

A magnetic resonance imaging (MRI) scan of the knee is a noninvasive way to take pictures of the knee joint and surrounding muscles and other tissues. Unlike x-rays and computed tomographic (CT) scans, which use radiation, MRI uses powerful magnets and radio waves. Knee pain is evaluated very well by MRI.  The MRI scanner contains the magnet. The magnetic field produced by an MRI is about 10 thousand times greater than the earth's. The magnetic field forces hydrogen atoms in the body to line up in a certain way (similar to how the needle on a compass moves when you hold it near a magnet). When radio waves are sent toward the lined-up hydrogen atoms, they bounce back, and a computer records the signal. Different types of tissues send back different signals. Single MRI images are called slices. The images can be stored on a computer or printed on film. One exam produces dozens or sometimes hundreds of images. Results are read by an on-site radiologist or a teleradiologist.

Knee MRI - Alternative Names and Explanations

MRI - knee, MRI of the Ankle, Magnetic Resonance Imaging of the Knee, MRI Lower Ext. Jnt. (knee/hip/ankle) w/o contrast 73721, MRI Lower Ext. Jnt. (knee/hip/ankle) with contrast 73722, MRI Lower Ext. Jnt. (knee/hip/ankle) with & w/o contrast 73723

Knee MRI - Benefits versus Other Diagnostic Tests

  • Knee pain is best evaluated by MRI. 
  • MRI is a noninvasive imaging technique that does not involve exposure to ionizing radiation.
  • MRI has proven valuable in diagnosing a broad range of conditions, including cancer, heart and vascular disease, and muscular and bone abnormalities.
  • MRI enables the discovery of abnormalities that might be obscured by bone with other imaging methods.
  • MRI allows physicians to assess the biliary system noninvasively and without contrast injection.
  • The contrast material used in MRI exams is less likely to produce an allergic reaction than the iodine-based materials used for conventional x-rays and CT scanning.
  • MRI provides a fast, noninvasive alternative to x-ray angiography for diagnosing problems of the heart and blood vessels.
