a noninvasive medical diagnostic technique in which the absorption and transmission of high-frequency radio waves are analysed as they irradiate the hydrogen atoms in water molecules and other tissue components placed in a strong magnetic field. This computerized analysis provides a powerful aid to the diagnosis and treatment planning of many diseases, including cancer MRI

magnetic resonance imaging n.
Abbr. MRI
The use of a nuclear magnetic resonance spectrometer to produce electronic images of specific atoms and molecular structures in solids, especially human cells, tissues, and organs.

magnetic resonance imaging (MRI)

A technique for forming detailed images of internal organs and tissue. It works by putting the patient inside a magnet, then using radio waves to locate atoms in the tissue. Final production of the image is done by a computer. (Compare x-ray and ultrasound.)

Note: MRI images are the most detailed that can be obtained.
