a From left to right: sagittal view, coronal view, and axial view of the voxel. b A typical fitted spectrum (in red). Indicated are myo-inositol (mI), choline (Cho), creatine (Cr), Glx and total NAA. Above the spectrum the residual signal after fitting is displayed. The baseline is displayed below the spectrum. c A typical MEGA-PRESS spectrum demonstrating typical fit of peaks for GSH and total NAA and aspartate.
