MRI
n 1: the use of nuclear magnetic resonance of protons to produce
proton density images [synonym: {magnetic resonance imaging},
{MRI}]

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.
