Exemplary images of the different ROIs used for this study. On the left-handed side, the CBV maps are presented (A and C); on the right-handed side, the DSC-MRI source data are presented (B and D). ROI1 = Circular ROI covering the tumor hotspot; ROI2 = Circular ROI covering the peritumoral region; ROI3 = Circular ROI covering the whole tumor region; ROI4 = Polygonal ROI covering the tumor hotspot; ROI5 = Polygonal ROI covering the peritumoral region; ROI6 = Polygonal ROI covering the whole tumor region. DSC-MRI = dynamic susceptibility contrast magnetic resonance imaging; CBV = cerebral blood volume; ROI = Region of interest
