This study was to characterize the regional neurochemical profiles of canine brain using NMRS, tissue extraction, and external simulated phantom concentration quantification. The occipital, frontal, and temporal lobes, thalami, cerebellar cortices, and spinal cords of adult beagles were obtained, and NMR samples were prepared using M/C extraction method. The metabolite concentrations in canine brain tissues were measured and compared with those found in human and rat brain. In addition, the cross peaks of brain metabolites were identified using 2D-COSY. This study demonstrated the absolute quantification of canine neuronal parts using MRS, with tissue extraction used to measure metabolite concentrations.
