A, CSI map of NAA shows decreased NAA signal intensity in the FSWM (straight arrows) and POWM (curved arrows).
B, Axial T2-weighted localizer image (2875/120) for MVS shows periventricular hyperintensities and cerebral atrophy.
C, MR spectrum (1500/136) (1) shows a normal NAA/Cr ratio and increased Cho/Cr ratios in left periventricular white matter. MR spectrum (2) shows substantially decreased NAA/Cr and increased Cho/Cr ratios in the left POWM.
