IDH2 and glioma: The StDev (p < 0.001), inhomogenity (p < 0.001), and range (p = 0.004) from the ROI-2 differed significantly between IDHwt gliomas and IDHmut gliomas and decreased with the IDH mutation, but the ADCmin (p < 0.001), P5 ADC (p = 0.008), and kurtosis (p = 0.012) in the IDHwt gliomas were lower than the other group (Table 5).
