Case 2. Case 2. Selected proton MR spectra (PRESS, 1500/136/1; nominal voxel size, 2 cm3) from the voxels indicated on the scout spin-echo T2-weighted MR image (2000/90/1; thickness, 10 mm) show moderate choline elevation (3.2 ppm), mild NAA loss (2.02 ppm), normal creatine peak (3.0 ppm), and an abnormally elevated peak at 3.6 ppm (myo-inositol) in the centrum semiovale. Spectra from the parasagittal cortical gray matter show only mild NAA loss. Similar proton MR spectroscopic findings in the centrum semiovale were found in case 1 Laura Farina et al.
