Magnetic Resonance Spectroscopy (MRS)
Similar term(s): Magnetic Resonance Spectroscopy (MRS).
A technique that uses a strong circular magnet for instance to identify the
chemical composition of diseased tissue.
MRS is one of several Nuclear Magnetic Resonance techniques. It is somewhat
different from MRI because it uses a continuous band of radio wave frequencies
to excite hydrogen atoms.
Physicians mainly use MRS to study the brain and disorders such as epilepsy,
Alzheimer's disease, brain tumors, and the effects of drugs on brain growth and
metabolism. The technique is also useful in evaluating metabolic disorders of
the muscles and nervous system.
