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

Figure 2

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