Magnetic resonance imaging (MRI) is introduced for medical diagnosis.

Magnetic resonance imaging (MRI) is introduced for medical diagnosis. In 1939, the American physicist Isidor Isaac Rabi showed how to study atoms and molecules through their magnetic properties. In 1946, two other Americans, Edward M. Purcell and the Swiss-born Felix Bloch, separately apply this nuclear magnetic resonance (NMR) method to solids and liquids. In 1971, researchers begin adapting NMR into magnetic resonance imaging, a non-invasive method to examine internal bodily structures, which becomes commercially available in 1980.
