The APT value and
the DCE-MRI parameters of Ktrans of peritumor edema may serve as a
potential biomarker assisted
grading of gliomas. The former may be more
conductive to differentiate grade Ⅱ and grade Ⅲ gliomas.
*Note: Using the one-way ANOVA and spearman’s
correlation coefficient for ranked data
Figure 1. ROC curve of APT value and
Ktrans value in peritumoral edema between grade Ⅱ and Ⅲ (AUC: 0.971 for APT, 0.714 for Ktrans;
95%CI: 0.89-1.00 for APT, 0.41-1.00 for Ktrans).
