Absolute quantitative MRS and quantitative MRI was used to assess the difference of NAWM between MS patients with non or a low number of MS lesions, MS patient with MS lesions, and healthy controls. Elevated levels of total glutamine + glutamate was observed in both investigate phenotypes of MS compered to healthy controls. In contrast elevated myo-Inositol, Choline containing compounds and lower levels of N-acetyl aspartate glutamate was only observed in NAWM of MS patients with several lesions. Furthermore a correlation between atrophy and increased total creatine + phosphocreatine was also observed in NAWM of MS patients.
