FIG 4. A–E, Comparison patterns of proton spectrum for both patients with BTG (patient 1, A and B; patient 2, C and D) obtained from voxels in normal areas (A and C) and tumoral areas (B and D) with peak assignments. The Cr peak is higher than the Cho peak in tumoral areas. These unusual patterns are different from that usually observed in a low-grade glioma (E). The 1.3 ppm resonance has been assigned to Lac in all spectra
