This paper is part of an ongoing longitudinal study of patients with NPC that includes quantitative measurements of metabolite levels at four locations in the brain. In a multivariate analysis, correlations were found between NAA and disease severity at 4 out of 4 locations studied, and between mI and disease severity at 1 location. NAA and mI also varied with age at some locations.
