Objective: In multireader, multicase (MRMC) receiver operating characteristic (ROC) studies for evaluating medical imaging systems, the area under the ROC curve (AUC) is often used as a summary metric. Methods We performed a systematic literature review from 2005 to 2013 inclusive to identify a minimum 50 studies. Owing to the limitations of AUC, plotting the average ROC curve to accompany the rigorous statistical inference on AUC is recommended.

Together they form a ⦠RATIONALE AND OBJECTIVES The authors demonstrated the use of mixture distribution analysis as an alternative to receiver operating characteristic (ROC) analysis in a clinical study, where independent verification of the imaging diagnosis is not always feasible. These differ from traditional ROC observer performance experiments by allowing for multiple abnormalities and observer responses per image, and by requiring correct localization for true positive events.

RJafroc implements software for analyzing the performance of artificial intelligence (AI) systems characterized by asearch-and-report strategy. Receiver operating characteristics (ROC) graphs are useful for organizing classifiers and visualizing their performance. With each method, the range of image quality and structure visibility can be considerable, depending on characteristics of the imaging equipment, skill of the operator, and compromises with factors such as patient radiation exposure and imaging time. The primary focus of this work has been on Receiver Operating Characteristic (ROC) analysis, which describes the accuracy of a diagnostic modality, for a particular clinical task, in terms of its trade-off between sensitivity and specificity [2-4]. Receiver operating characteristic (ROC) methodology is widely used in evaluating medical imaging modalities.
