From: A case report of pseudoprogression followed by complete remission after proton-beam irradiation for a low-grade glioma in a teenager: the value of dynamic contrast-enhanced MRI

Figure 4

Nine months after irradiation: complete disappearance of the contrast enhancement (left) and no detectable Permeability (right). [A] T1-weighted transaxial MR image after administration of iv Gd-DTPA and [B] the superimposed Permeability map, with no contrast enhancement or detectable microvascular leakage. To be noted, a subtle hypersignal, pre-existing to the irradiation, as a post-operative modification (yellow arrow).
