This paper describes the effect of a computer-aided detection (CAD) system's false positive marks on observer performance when interpreting films containing lung cancer. We compared the location/no location chosen initially by the radiologists and the stability or change in location that followed the provision of the CAD information. We found a difference in radiologists' behavior that depended on whether the radiologists' initial interpretation was a true positive or a false positive detection. When the radiologist made an incorrect initial decision, that decision was less stable than when the initial decision was correct.
