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

Table 3

Intragroup comparisons of DCE-MRP metrics measured from PT, NNA, and CLNA are given. Among the permeability metrics of PT, the differences of Ve and IAUC from both NNA and CLNA and the difference of Kep from NNA are significantly different.
