This study was designed to measure T1 and T2 relaxation times of the singlets in normal brain at 7T. Our results demonstrated that the T1 relaxation values of total creatine (tCr)-CH3 and N-acetyl aspartate (NAA) in the parietal white matter significantly increased at 7T compared to 3T, while the T1 of Choline-containing compounds (Cho) was similar between field strengths.
