The main resonances correspond to N-acetylaspartate (NAA, 2.0 ppm), glutamine/glutamate (Glx, 2.1–2.5 ppm), creatine/phosphocreatine (Cr, 3.02 ppm), choline-containing compounds (Cho, 3.2 ppm), and myo-inositol (Ins, 3.55 ppm). The initial spectrum shows an increase in the glutamate/glutamine region and a decrease in the myo-inositol and choline resonances. These abnormalities normalized after liver transplantation. Normal NAA indices are seen in both examinations. A. Rovira et al. AJNR Am J Neuroradiol 2008;29: ©2008 by American Society of Neuroradiology
