Magnetic resonance spectroscopy (MRS) is a noninvasive means of obtain
ing metabolic information complementary to magnetic resonance imaging.
Its potential is particularly interesting in tissue characterization
and follow-up of brain lesions, We present here a review of clinical a
pplications together with a short development of the fundamental princ
iples, From a review of the literature, and our own experience, we dis
cuss the role of MRS in clinical neuroimaging. Despite the small numbe
r of clinical applications validated to date, MR is today a highly use
ful research tool.
