Magnetic resonance spectroscopy profile of the pons after traumatic brain injury. (a) Normal profile. The peak of N-acetyl-aspartate (NAA) is higher than the peaks of choline (Cho) and creatine (Cr). (b) Neuronal loss profile. The NAA peak is decreased, nearly to the level of the Cr peak. The NAA/Cr ratio is lower than in panel a. (c) Gliosis profile: increased Cho peak with no change in the Cr or NAA peak. Adapted from [17].
