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

Table 5

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