1H MRSI spectra (TR/TE = 1800/135 ms) obtained from dorsolateral prefrontal cortex (left), posterior-parietal cortex (middle) and frontal white matter (right) indicated on the oblique-axial MRI in Fig. 1 of a 27-year-old alcohol-dependent cocaine addict abstinent for 4 months. The three major peaks are from n-acetyl-containing metabolites (primarily N-acetylaspartate or NAA) at 2.02 p.p.m., creatine-containing metabolites (Cr) (primarily creatine and phosphocreatine) at 3.03 p.p.m. and from choline-containing metabolites (Cho) (primarily glycerophosphocholine and phosphoch oline) at 3.23 p.p.m.
