Fig 3. T2-weighted MR, selected spectra, and metabolic images of Cho, Cr, NAA, and lactate (Lac) in a typical demyelination case (metachromatic leukodystrophy). T2-hyperintense white matter regions are characterized by increased Cho and decreased NAA. The gray matter spectrum (voxel 4) also shows a somewhat decreased NAA/Cho ratio. PPM indicates parts per million.
