S. Grand et al., PROTON MAGNETIC-RESONANCE SPECTROSCOPY - A METABOLIC APPROACH TO BRAIN-TUMORS AND THEIR FOLLOW-UP AFTER EXTERNAL RADIATION, La Revue de medecine interne, 18(11), 1997, pp. 865-875
The same physical principles are at the basis of magnetic resonance sp
ectroscopy (MRS) and magnetic resonance imaging (MRI). Proton MRS is e
asily performed with clinical magnets (greater than or equal to 1.5 T)
and may be added to routine MRI studies to provide metabolic informat
ion on pathological tissues. It represents an important tool to detect
several metabolic compounds. The article will review the current stat
us of proton MRS with a particular emphasis upon its clinical utility
for the diagnosis of brain tumors and for the evaluation of the effica
cy of radiotherapy.
