The patient in Example 3 is called back for CT to confirm the Lung Nodule found in Example 3. The patient undergoes CT of the​ Thorax and the initial chest radiograph and CT slices are sent to a more comprehensive CAD device for processing. Findings are​ detectedandanalysesareperformedthatcorrelatefindingsfromthetwocollectionsofdata.PortionsofthepriorCADreport(Example​ 3) are incorporated into this report.​
