  magnetic resonance imaging \mag*net"ic res"on*ance im"ag*ing\ n.
     (Medicine)
     a medical diagnostic procedure utilizing the phenomenon of
     nuclear magnetic resonance to generate images of internal
     parts of the body. It depends on the differential absorption
     of electromagnetic radiation by different types of living
     tissue in a magnetic field. It is complementary to X-ray
     imaging in that the softer tissue show more prominently in
     magnetic resonance images, rather than bone, as with X-rays.
     It is a non-invasive procedure, allowing such images to be
     obtained without penetration of the tissue by objects. It is
     abbreviated MRI. As with computerized tomography, the
     results are usually presented as images of sequential planar
     sections of that part of the body of concern to the
     physician.
