In addition to performing conventional receiver operating characteristic (ROC) analysis (localization information ignored), the software also performs free-response receiver operating characteristic (FROC) analysis, where lesion localization information is integral to the analyzed data. In the free-response receiver operating characteristics (FROC) analysis for lesion detection, FocalNet achieved 89.7% and 87.9% sensitivity for index lesions and clinically significant lesions at one false positive per patient, respectively. Annals of Internal Medicine 94:555-600. In determining lesion resectability, the mean areas under the receiver operating characteristic curves were 0.96 and 0.81 (p = .01) and the positive predictive values were 86.5% and 76% (p = .02) for MR imaging and helical CT, respectively. Receiver operating characteristic (ROC) analysis is such a tool that can help clinicians evaluate the accuracy of their diagnoses of a disease, and many other binary decisions (6, 7). Owing to the limitations of AUC, plotting the average ROC curve to accompany the rigorous statistical inference on AUC is recommended. Traditional statistical comparison of different imaging modalities only analyzes ROC measures of a single radiologist from each modality.
