Title
Study of Effectiveness of Computer Aided Detection of Missed Cancers
Summary
On chest radiographs, skilled radiologists have been shown in several studies to miss up to 1/3 or more of cancers that can be detected in retrospect. Computer aids to detection have been shown to enhance this detection rate, resulting in up to 21% more cancers detected. The goal is to determine whether radiologists using the most modern CAD systems would have been able to detect the cancers detected in the PLCO on the radiograph obtained one year prior to their actual detection if they had used computer aids.
Aims

The specific aim is to test a modern computer program for the detection of lung cancer on the one year prior chest radiographs of subjects who were identified to have a lung cancer on their next screening chest radiograph.
