performed on brain sections (100 μm thickness) used for ex vivo MRI (corresponding to Fig. 5A–B, ex vivo panel). Necrotic areas (black/white arrows) match the regions of high ECS (>70 %) estimated using MRI (Fig. 5). Similarly, regions of low ECS appear to match areas of tumor infiltration in Gray and White Matter.
