Definition of magnetic resonance imaging in US English:

magnetic resonance imaging

noun

Medicine
  • A form of medical imaging that measures the response of the atomic nuclei of body tissues to high-frequency radio waves when placed in a strong magnetic field, and that produces images of the internal organs.
