In this study, a novel macaque model of neuro-AIDS was employed to investigate the longitudinal cerebral metabolite alternation in asymptomatic patients with in vivo MRS at 3T. The results demonstrated that NAA was reduced significantly in the acute phase and Glx was reduced significantly in both acute and chronic phases after the SIV inoculation. The progressive alternations in NAA and Glx correlated significantly with the CD8 T cell %.
