Advanced MRI imaging for medulloblastoma. Axial FLAIR (a) and DWI (b) display an extra-axial mass occupying the lateral and retrocerebellar regions, demonstrating a high signal in FLAIR with restricted diffusion in DWI. Axial T1 after contrast administration (c) demonstrates strong heterogeneous contrast enhancement of the mass. DSC-MR perfusion maps (df) show increased vascularization in the mass, with increased blood flow (d) and high value of rCBV (e) of the mass than the normal parenchyma. DWI diffusion-weighted image, DSC dynamic susceptibility contrast-enhanced, rCBV relative cerebral blood volume
