The role and position of proton magnetic resonance spectroscopy have been studied in diagnosis of brain diseases. 114 patients with various diseases of the brain have been examined (multiple sclerosis--41, insults of different etiology--17, encephalopathy--12, AIDS infection--23, epilepsy--12, reduction of the intellectual ability of various etiology--9). MR tomography and 1HMR Spectroscopy have been done with Magnetom "Vision", 1.5 T (Siemens) in the CRIRR, St. Petersburg. To get a proton magnetic-resonance specter, SVS_STEAM, SVS_STEAM-20 and SVS_SE-135 sequences have been used with the following parameters: TR 5000 ms, TE 10, 20 and 135 ms respectively, number of acquisitions--100. Typical changes of metabolities in every group have been revealed. The performed examinations have shown that proton magnetic resonance spectroscopy enables to widen our know-ledge about the nature of pathologic changes, that grow with different diseases of the brain.
