1H MR spectrum acquired at 3.0 T from a volume of interest in occipital lobe (20 × 20 × 20 mm3, T1-weighted axial image) of healthy subject with the STEAM sequence (repetition time msec/echo time [TE] msec = 5000/8; 128 repetitions). tNAA = total N-acetylaspartate (NAA), tCr = total creatine (Cr), tCho = total choline, Glu = glutamate, Gln = glutamine, mIns = myo-inositol, MM = macromolecules.
