Abnormalities in ratios of brain metabolite peak areas were previously measured via magnetic resonance spectroscopy (MRS) at 1.5T in the pons and basal ganglia, and in bilateral hippocampus of Gulf War Syndrome patients. The original veterans of the Seabees cohort recently participated in a follow-up study at 3T. We report our findings on significant differences in NAA/Cr ratio between Syndrome II veterans and control subjects.
