A: Post-gadolinium T1-weighted MRI overlaid with an image of the resected tumor including the delineation of the tissue blocks (left), example map of rCBV values (with a range of 1 to 25) of the areas occupied by the analyzed tumor blocks (top right), and example color map representing the MVA values (with a range from 0.0 to 6.5μ²) present in each analyzed block (below right). Blank blocks are not included due to lack of histopathological information. Example of patient W33 from the Ivy GAP database. B: Boxplot showing the significant differences of mean rCBV (left) and maximum rCBV (right) between the group with presence of microvessels and the group with absence of microvessels
