New Enhancement beyond Radiation Field Improves Survival Prediction in Patients with Post-Treatment High-Grade Glioma

Figure 2

Comparison of ROC curve analyses for different combinations of clinical and MR variables for predicting poor OS. The combination of Clin + Conven MRI + NERF presents the high diagnostic performance (AUC 0.924; 95% CI 0.881, 0.967), with significant level of to any other combinations. ROC, receiver operating characteristic; AUC, area under ROC curve; Clin = age + histological grade; Conven MRI = nonenhanced T2/FLAIR hyperintensity lesions + enhancement of residual cavity wall; NERF, new enhancement beyond the radiation field.
