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

Figure 1

TM is seen at the upper border of the resection cavity in a patient operated for grade 3 glial mass (a). Ktrans, Kep, IAUC maps, and tissue contrast-time curve of DCE-MRP are seen (b). ROIs are placed at ERC, NNA, and CLNA (b). Enhancing area shows the highest permeability with the highest in Ktrans, Ve, and IAUC values and the lowest in Kep values, compared to the other areas.
