Example high and low risk, high and low-grade tumors. (A T1 post contrast & B ADC map) high risk and (C T1 post contrast & D ADC map) low risk Pilocytic astrocytoma, respectively showing elevated ADC skew and kurtosis in the tumor region. (E, F) high risk and (G, H) low risk medulloblastomas, respectively, showing increased ADC kurtosis. Tumor regions are highlighted with white arrows.
