基本原理和目标。计算机辅助诊断 (CAD) 的开发是为了确保放射科医生在胸部 X 光检查中考虑到可能代表癌症的可疑局灶性混浊。尽管 CAD 的开发并不是为了抵消搜索满意度 (SOS) 效应，但它可能是一种有效的干预措施。本研究的目的是确定理想化 CAD 是否可以减少胸部 X 线摄影中的 SOS 效应。材料和方法。 16 名观察者对 57 张胸部 X 光片进行了两次读取，其中一半显示出多种自然异常，一次有模拟肺结节，一次没有。解释过程中提供了模拟 CAD 提示，准确无误地指向添加的模拟结节。估计每个观察者在每种治疗条件下用于检测天然异常的 ROC 曲线下面积。除了测试之外，对于 CAD 提示下的 SOS 效果，我们还将结果与之前的 SOS 研究结果进行了比较。结果。 CAD 实验中的 SOS 中报告的结节明显多于原始 SOS 实验（49 比 43，P
Rationale and Objectives. Computer-aided diagnosis (CAD) has been developed to ensure that the radiologist considers suspect focal opacities that may represent cancer in chest radiography. Although CAD was not developed to counteract the satisfaction of search (SOS) effect, it may be an effective intervention to do so. The objective of this study is to determine whether an idealized CAD can reduce SOS effects in chest radiography. Materials and Methods. Fifty-seven chest radiographs, half of which demonstrated diverse, native abnormalities were read twice by 16 observers, once with and once without the addition of a simulated pulmonary nodule. Simulated CAD prompts were provided during the interpretation, which unerringly pointed to the added simulated nodule. Area under the ROC curve for detecting the native abnormalities was estimated for each observer in each treatment condition. In addition to testing,, for the SOS effect in the presence of CAD prompts, results were compared to those of a previous SOS study. Results. Significantly more nodules were reported in the SOS with CAD experiment than in the original SOS experiment (49 versus 43, P
