  Left prefrontal cortex Right prefrontal cortex
  Metabolite concentration (in IU) (CRLB) Metabolite ratio (/Cre) Metabolite concentration (in IU) (CRLB) Metabolite ratio(/Cre)
Glx 5.673 (12 %) 1.129 7.424 (8 %) 1.576
Cre 5.023 (3 %) 1.0 4.710 (3 %) 1.0
t-Cho 1.238 (3 %) 0.246 1.217 (3 %) 0.258
NAA + NAAG 6.783 (3 %) 1.350 5.802 (3 %) 1.232
mI 3.815 (5 %) 0.760 3.295 (5 %) 0.699
  1. The MRS spectrum from the left prefrontal cortex shows lower concentrations of Glx compared with the opposite side. Glutamatergic hypometabolism correlated with a distinct hypometabolism in FDG-PET in this region; TR = 3000; TE = 30; NS = 64; voxel size = 8.0 mL. Abbreviations: CRLB = Cramér-Rao lower bounds; IU = Institutional Units; Glx = glutamate + glutamate; Cre = creatine; t-Cho = phosphorylcholine + glycerophosphorylcholine; NAA + NAAG = N-acetylaspartate + N-acetyl-aspartyl glutamate; mI = myo-inositol
