Diagnostic Performance of Dynamic Contrast-Enhanced 3T MR Imaging for Characterization of Orbital Lesions: Validation in a Large Prospective Study

ROC curves of each DCE and ADC parameter when distinguishing malignant from benign lesions. The x-axis refers to 1-specificity, and the y-axis refers to the sensitivity. The black line represents the AUC; the blue area, the 95% confidence interval; and the dotted red line, the diagonal, ie, an AUC of 0.5.

ROC curves of each model when distinguishing malignant from benign lesions. The x-axis refers to 1-specificity; the y-axis, to the sensitivity. The black line represents the AUC; the blue area, the 95% confidence interval; and the dotted red line, the diagonal, ie, an AUC of 0.5. A indicates model A with DCE parameters only; B, model B with DCE and ADC parameters combined; C, model C with DCE and morphologic imaging parameters combined; D, model D with DCE, ADC, and morphologic imaging parameters combined; E, model E with morphologic imaging parameters only; F, model F with ADC only; and G, model G with ADC and morphologic imaging parameters.
