FIG 2. Proton spectra from same subject and voxel locations as shown in figure 1. The dark line represents the LCModel fit of the spectrum. The assignments of the principal peaks (in ppm) in the in vivo spectrum are as follows: NA = NAA (2.01) + NAAG (2.05), Cr (3.03), Ins (3.56). The complex multiplets of Glu and Gln, whose sum is Glx, are located at approximately 2.1 to 2.5 ppm and 3.7 to 3.8 ppm (see [41]).
A, Precentral gyrus.
B, Cuneus gyrus.
