1H MRSI raw (light jagged black trace), LCModel fit (red), and baseline (smooth black) spectra for a representative voxel acquired as in Fig. 1. Principal resonances are labelled for N-acetyl-asparatate (NAA) and N-acetyl-aspartyl-glutamate (NAAG), glutamate (Glu) and glutamine (Gln), creatine (Cr) and phosphocreatine (PCr), choline-compounds (Cho), and myo-inositol (mI). Both Glu and Glx were fit by LCModel with < 20% standard deviation.
