In patients with mild traumatic brain injury (mTBI), our aim was to find correlations between clinical scores and proton metabolite concentrations in different parts of the brain. 21 patients within 2-3 days after injury and 21 matched volunteers were examined with cognitive tests, MR spectroscopic imaging (CSI) and single-voxel spectroscopy. NAA in lateral frontal areas was decreased in all patients, in brain stem only in the individuals with unconsciousness. Significant positive correlations of frontal lateral NAA with cognitive test results were observed. CSI revealed further spatial metabolite information. Our results help resolve the involvement of different brain parts during mTBI.
