Receiver Operating Characteristic (ROC) Curve Analysis for Medical Diagnostic Test Evaluation. AUC =0.5 means the chance discrimination that curve located on diagonal line in ROC space. It provides a measure of the diagnostic performance of an imaging modality by plotting the sensitivity versus the specificity for a wide and continuous range of decision criteria. The performance of gadolinium‐ethoxybenzyl‐dieth‐ylenetriaminepentaacetic acid (Gd‐EOB‐DTPA) and superparamagnetic iron oxide (SPIO) particles in detecting liver cancer was compared using alternative free‐response receiver operating characteristic (AFROC) analysis, which allowed observers to indicate both the confidence level and the locations of all perceived abnormalities. Unpaired t test was used to compare the mean ADC values for different lesions, and statistical significance was set at P < 0.01. Owing to the limitations of AUC, plotting the average ROC curve to accompany the rigorous statistical inference on AUC is recommended.
