Figure 2: Representative T1-weighted spectra acquired using spectralspatial pulse at TE of 90 ms (right) and the corresponding voxel location (left top) from a volunteer. The peak heights of metabolites were used to estimate the T1values for Cho, tCr-CH3 and NAA (bottom). The corresponding T1 values of Cho, tCr-CH3 and NAA were 1.15 s, 1.80 s and 1.81s.
