Note.—Metabolites’ resonance intensities are expressed as ratios to the Creatine/Phosphocreatine (Cr, at 3.05 ppm) signal intensities.

mI = myoinositol, at 3.56 ppm; Cho = choline, at 3.05 ppm; NAA = N-acetyl aspartate, at 2.01 ppm; Lac = lactate, at 1.33 ppm. The signal at 0.9 ppm could be either related to lipids or to branched chain amino acids.
