我们测试了是否满意的搜索（SOS）的影响发生在计算机断层扫描（CT）检查的胸部检测本地异常产生的模拟肺结节。进行了两个实验。在第一个实验中，70个CT检查，一半显示不同的，微妙的异常，一半显示没有原生病变，由18名放射科住院医师和研究员在两种实验条件下阅读：有和没有肺结节。在第二个实验中，许多检查被替换，以包括更突出的原生异常。另外14名放射科住院医师和研究员阅读了这一集。在这两个实验中，研究了自然异常的检测。使用经验和适当的ROC模型估计每个阅片者-治疗组合的ROC曲线面积。其他分析集中在无异常CT切片范围的决策阈值和视觉搜索时间。获得了机构审查委员会的批准和32名参与者的知情同意书。当增加肺结节时，观察者更经常错过各种各样的原生异常，但假阳性反应也更少。ROC面积没有变化，但决策标准变得更加保守。SOS对决策阈值的影响伴随着无异常CT切片范围搜索时间的减少。胸部CT检查中的SOS效应与腹部对比检查中发现的SOS效应相似，涉及诱导性视觉忽视。
We tested whether satisfaction of search (SOS) effects occur in computed tomography (CT) examination of the chest on detection of native abnormalities is produced by the addition of simulated pulmonary nodules. Two experiments were conducted. In the first experiment, seventy CT examinations, half that demonstrated diverse, subtle abnormalities and half that demonstrated no native lesions, were read by 18 radiology residents and fellows under two experimental conditions: presented with and without pulmonary nodules. In a second experiment, many of the examinations were replaced to include more salient native abnormalities. This set was read by 14 additional radiology residents and fellows. In both experiments, detection of the naturally abnormalities was studied. ROC curve areas for each reader-treatment combination were estimated using empirical and proper ROC models. Additional analyses focused on decision thresholds and visual search time on abnormality-free CT slice ranges. Institutional review board approval and informed consent from 32 participants were obtained. Observers more often missed diverse native abnormalities when pulmonary nodules were added but also made fewer false positive responses. There was no change in ROC area, but decision criteria grew more conservative. The SOS effect on decision thresholds was accompanied by a reduction in search time on abnormality-free CT slice ranges. The SOS effect in CT examination of the chest is similar to that found in contrast examination of the abdomen, involving induced visual neglect.
