5. Figure 4
Example of perception error. Axial computed tomography images with contrast from a patient with malignant pleural mesothelioma with a large right pleural effusion and discontinuous areas of pleural thickening representing tumor. Areas perceived as tumor by the two reviewers are represented by yellow (A) and red (B) contour lines, respectively, and the resulting difference in calculated tumor volume is as depicted in the three-dimensional volume-rendered images (C).

7. Figure 5
Example of limited distinction between tumor and adjacent structures. (A and D) Depiction of corresponding sets of axial computed tomography images obtained without intravenous contrast in a patient with right-sided malignant pleural mesothelioma with similar density and therefore poor contrast among tumor, chest wall musculature, liver, and the mediastinal vascular structures (white arrows) demonstrating discrepant tumor delineation by the two reference radiologists, respectively. The resulting difference in calculated tumor volume is apparent by comparing the respective three-dimensional volume-rendered images (B and C).
