FIG 2. Examples of ¹H MR spectra (2000/30) obtained at 3 T (top) and at 1.5 T (bottom) from the posterior cingulate voxel. Glu + Gln peak resonances are better resolved at 3 T than at 1.5 T. The resonance at 3.4 ppm that is more prominent in the 1.5- than in the 3-T spectra is scyllo-inositol and/or taurine (3).
