Within session and between session variability of metabolites for whole brain proton spectroscopy.

Individual region of interest measurements for within session reproducibility obtained in the first and second imaging sessions in 17 and 16 subjects respectively, and the between session reproducibility for those 22 subjects who underwent imaging at both sessions. Data displayed are percentage coefficient of variation for metabolite ratios (Choline (Cho)/Creatine (Cr), N-Acetyl aspartate (NAA)/Choline and NAA/Cr.
