Phases of methodology: I) MRI Process conducted by the Segmentation Service included in the ONCOhabitats platform; II) Image overlay and mask generation; III) Coregistration and IV) Calculation of imaging markers. A Required inputs for the MRI process (T1, T1c, T2, Flair and DSC); (B) Preprocessing of the MRIs; (C) Classic segmentation of the lesion into tumor, edema and necrosis; (D) DSC perfusion quantification and rCBV map calculation. E Inputs to generate the block mask; (F) Image overlay process for mask generation; (G) Block mask; (H) Overlay of the rCBV map and block mask; (I) Calculation of imaging markers (rCBVmean and rCBVmax) in each tissue block
