To obtain absolute concentrations of metabolites from spectra obtained at longer echo times, the knowledge of both the J-modulation and T2 relaxation times is required. The T2 relaxation times at 7 T have been reported previously for the methyl protons of N-acetylaspartate (NAA) and the methyl protons of total creatine (creatine + phosphocreatine, tCr). The aim of this study was to measure T2 relaxation times in different brain regions of the singlets and J-coupled metabolites.
