IDH1 and glioblastoma: Using instead the PC-to-PE ratio led to an increase in contrast against healthy tissues in these specific cases, and showed lower values in mutant-IDH tumors (both LGGs and the HGG with WHO grade 3) compared to wildtype-IDH tumors (glioblastomas in the HGG group) in Figure 7, thus hinting at a potential discrimination of IDH species [however, with reversed ratios compared to (7)].
