Materials and Methods: The study was approved by the institutional review board of The University of Sydney. Informed consent was obtained from all the participating radiologists. Thirty radiologists with varying experience levels (median = 7 years) read sixty chest computed tomography (CT) scans. Thirty cases had surgically or biopsy-proven lung cancer and the remaining thirty were cancer-free cases. The cancer cases were validated by four expert radiologists who located the malignant lung nodules. Reader performance was evaluated by calculating sensitivity, location sensitivity, specificity, and area under the receiver operating characteristic curve (AUC). In addition, sensitivity at fixed specificity = 0.794 was computed from each reader's estimated receiver operating characteristic curve.
