Fig. 9.10.
Examples of (a) GABA- and (b) glutathione-edited spectra using the MEGA-PRESS pulse sequence. TR 2 s, voxel size 3.5×3.5×3.5 = ~43 cm3, centered on the anterior cingulate gyrus, with TE 68 ms for GABA and 130 ms for GSH. Scan time was 8 min 32 s for GABA and 17 min 4 s for GSH. Note that in (a) glutamate/glutamine (Glx) coedit with GABA, and in (b) the aspartyl resonances of NAA coedit with GSH.
