T1 and T2 relaxation time values vary in different regions and magnetic environments. Though T1 and T2 correction factors are necessary in absolute quantification, previous MRS studies mainly obtained the values from literature since the measurements require much time to be conducted. In this 1H-MRS study of aging, T1 and T2 values were measured within the sampling population in order to achieve higher accuracy at 3-Tesla. This study demonstrated the measurements only take reasonable amount of time with our method employed.
