Fig. 4From: Dual-energy spectral CT quantitative parameters for the differentiation of Glioma recurrence from treatment-related changes: a preliminary studyGraphs show receiver operating characteristic curves of λHU, Zeff-gli, ICgli and Zeff-N in venous phase for differentiating glioma recurrence from treatment-related changes in patients. The venous Zeff-N had the highest AUC (0.931), with the optimal threshold of 1.04 AUC = area under the curveBack to article page
