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

(Medicine) 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. Abbreviation: MRI

magnet′ic res′onance im`aging

a process of producing images of the body regardless of intervening bone by means of a strong magnetic field and low-energy radio waves. Abbr.: MRI

magnetic resonance imaging

The use of nuclear magnetic resonance to produce images of the molecules that make up a substance, especially the soft tissues of the human body. Magnetic resonance imaging is used in medicine to diagnose disorders of body structures that do not show up well on x-rays. See more at nuclear magnetic resonance.
