SATISFACTION OF SEARCH IN DIAGNOSTIC RADIOLOGY

这项提议的长期目标是理解 在放射学检查中对多重异常的感知 并制定提高诊断准确率的策略 和病人的结果。未能检测到异常是最大的 诊断成像中的常见错误类别，通常 被医学界认为是最严重的。许多. 这些错误被归因于搜索的满足感， 当由于发现另一个 异常情况达到了搜索的目的。绝大多数人 减少差错的技术研究和临床努力是 专注于改善图像质量，以便异常情况 更显眼。另一种方法是学习，从而提高， 解释过程本身。到目前为止，口译是最关键的 租约了解诊断过程的一部分。我们是世界上 世界上很少有实验室追求还原检测的目标 通过更好地理解潜在的知觉来犯错误 涉及的流程。我们提出了六个实验来找出 导致放射科医生在视觉上忽略了图像的某些区域， 评估目前用于研究的错误分类系统 搜索(SOS)错误的满意度，并测试是否系统性 自我推销可以减少这种类型的错误。这项研究 方法学将包括接收者工作特性(ROC) 曲线分析、眼位记录和其他心理生理检查 方法：研究方法。从这些研究中获得的理解可能会导致 SOS错误的减少。这种误差的减少可能是最大的 随着非放射科医生对图像解释的增加， 他们主要受临床怀疑的驱使，更倾向于 容易受到涉及意外异常的错误的影响。

The long-term objective of this proposal is to understand how the perception of multiple abnormalities in a radiology examination occurs and to develop strategies for improved diagnostic accuracy and patient outcome. Failure to detect an abnormality is the most common class of error in diagnostic imaging and generally considered the most serious by the medical community. Many of these errors have been attributed to 'satisfaction of search,' which occurs when a lesion is not reported because discovery of another abnormality has satisfied the goal of the search. The vast majority of technical research and clinical endeavor to reduce error is concentrated in improving image quality so that abnormalities are more visible. Another approach is to study, and thereby improve, the interpretive process itself. Interpretation is the most crucial, yet lease understood part of the diagnostic process. We are one of the few laboratories in the world pursuing the goal of reduce detection errors through a better understanding of the underlying perceptual processes involved. We propose six experiments to find out what causes radiologists to visually neglect some areas of images, to evaluate the error classification system currently used to study satisfaction of search (SOS) errors, and to test whether systematic self-promoting can reduce this type of error. The research methodologies will include receiver operating characteristic (ROC) curve analysis, eye-position recording and other psychophysical methods. The understanding gained from these studies could lead to a reduction in SOS error. This reduction in error could be most significant with increased image interpretation by non-radiologists, who, being principally driven by their clinical suspicion, are more susceptible to errors involving unanticipated abnormalities.
