Proton magnetic resonance spectroscopy(1H-MRS), which provides biochemical information in not only visible lesions on conventional MR imaging but also normal appearing white matter(NAWM), has extended the genesis of multiple sclerosis(MS) in several important directions. First, serial 1H-MRS studies reveal dynamic regional biochemical alterations in plaques during the course of the illness. Second, axonal damage may occur at early stage. Third, neuronal loss can be substantial in the gray matter. Fourth, NAWM shows widespread biochemical involvement prior to detection on MRI. Fifth, severities of neuroaxonal involvement significantly correlate with neurological dysfunction. 1H-MRS will provide more detailed information than conventional MRI, and could be beneficial in monitoring effects of therapeutic interventions in MS.
