放射学中的一个子集未读错误(假阴性反应)被归因于“搜索满足感”，即在检测到初始病变后仍未检测到病变时发生的。这一现象还没有在实验实验室中得到研究。这项研究的一个主要目标是开发一种研究搜索满意度的程序或范式。作者测量了在添加模拟结节病变之前和之后图像中对自然病变的检测准确性。模拟病变和自然病变在空间上没有重叠，自然异常与结节和无结节在物理上是相同的。只分析了与本地病变相关的反应。用极大似然法和刀刀法估计受试者工作特征(ROC)曲线的精度参数。随着结节的增加，Az和De‘’测量的单个ROC曲线的平均感知准确度显著降低(分别为t=2.364，p=0.025，t=2.648，p=0.017)。合并ROC曲线的Az和De‘参数也有相似的影响(t=1.573，p=0.080；t=1.934，p=0.047)。研究结果显示，患者对搜索结果的满意度很高，但对本土病变的感知准确度有所降低。
A subset of underreading errors (false-negative responses) in radiology has been attributed to "satisfaction of search", which occurs when lesions remain undetected after detection of an initial lesion. This phenomenon has not been studied in the experimental laboratory. A primary goal of this study was to develop a procedure or paradigm to study satisfaction of search. The authors measured detection accuracy for native lesions in images before and after the addition of a simulated nodular lesion. Simulated and native lesions were not spatially superimposed and the native abnormalities were physically identical with and without the nodules. Only responses related to the native lesion were analyzed. Accuracy parameters of receiver operating characteristic (ROC) curves were estimated by the method of maximum likelihood and jackknife. The average perceptual accuracy of the individual ROC curves as measured by Az and de'' was significantly reduced with addition of the nodules (t = 2.364, p = 0.025, t = 2.648, p = 0.017, respectively). Az and de'' parameters of the pooled ROC curve showed a similar effect (t = 1.573, p = 0.080; t = 1.934, p = 0.047, respectively). The results indicated a substantial satisfaction-of-search effect, with diminished accuracy in perception of native lesions.
