IDH2 and astrocytoma (excluding glioblastoma): A study compared the ADCs of astrocytoma patients and found that the rADC (IDH-mutated = 1.88 ± 0.41; IDH-wildtype = 1.37 ± 0.31; p < 0.001) and ADCmin (IDH-mutated = 1.21 ± 0.27, IDH-wildtype = 0.87 ± 0.18; p < 0.001) of IDH-mutated astrocytomas were significantly higher than those of wildtype astrocytomas [50] (Table 2).
