magnetic resonance imaging (MRI)
1. A type of diagnostic radiography using electromagnetic energy.

Certain atomic nuclei with an odd number of neutrons, protons, or both are subjected to a radio-frequency pulse, causing them to absorb and release energy.

2. A non-invasive method of imaging the body and its organs; as well as, studying tissue metabolism.

More details about MRI

The body is placed in a magnetic field which causes certain atomic nuclei to align in the direction of the field. Pulses of radio-frequency radiation are then applied; interpretation of the frequencies absorbed and re-emitted allows an image in any body plane to be built up.

Different tissues; for example, fat and water, can be separately identified and, if the resonance signal for the fat is suppressed, then only the signal from any abnormalities in the fat can be identified.

Many diseases result in a rise in the water content of tissues; so, MRI, or magnetic resonance imaging, is a valuable test for identifying certain diseases.
