Follow-Up of High-Grade Glial Tumor; Differentiation of Posttreatment Enhancement and Tumoral Enhancement by DCE-MR Perfusion

Figure 3

Postcontrast axial T1 (a) and axial T2 images (b) show PT at ERC in a patient operated for grade 4 glial mass. Ktrans, Kep, IAUC maps, and tissue contrast-time curve of DCE-MRP are seen (c). ROIs are placed at ERC and CLNA. Enhancing areas have higher permeability with increased Ve and IAUC but similar Ktrans values compared to the CLNA.
