Panel A: High-resolution post-contrast agent T1-weighted image. Panel B: H&E staining of a centrally located tissue slice approximately corresponding to the central slice of the MRI study. Panel C: Model selection map. Yellow indicates model 3 acceptance (regions associated with highly leaky vasculature along with backflux), dark red indicates model 2 acceptance (bordered model 3 regions, showing leakage at reduced rates) and red indicates model 1 acceptance (normal nonleaky brain tissue). Note the anatomical agreement in the position and distribution of the tumor mass and boundary between the model 3 region, T1 MRI and H&E images. The rat brain is approximately 1.5 cm across (transverse direction).
