  1. Mean and standard error (SE) of metabolite levels for glial and PNET tissue with statistical significance levels from two-tailed students t-tests assuming unequal variance shown for significant metabolites. All metabolite quantities were divided by the fitted spectral area between 0.5 and 4.5 ppm. Tau – Taurine, Suc – Succinate, s-Ins – scyllo inositol, PEth – phosphorylethanolamine, PC – phosphorylcholine, m-Ins – myo-inositol, Lac – lactate, Gly – glycine, GPC – glycerophosphorylcholine, Gln – glutamine, Glu – glutamate, Cr – creatine, Cho – choline, Asp – aspartate, Ala – alanine, Ace – aspartate, NAA – N-acetylaspartate.
