M
agnetic Resonance Imaging (MRI) is a process developed in
the 1980's as a way to
identify tissue abnormalities. It is, essentially,
the same thing as NMR, but patients were
frightened by the term "nuclear." The basis of
MRI is that hydrogens in water behave
differently in different tissues. By placing the
patient's body between the poles of a large
electromagnet, the variations of a proton's magnetic
resonance behavior from normal
patterns may be detected and used to make a diagnosis.
