SATISFACTION OF SEARCH IN DIAGNOSTIC RADIOLOGY

本提案的长期目标是了解 在放射学检查中感觉到多种异常 并制定提高诊断准确性的策略 和患者结局。 如果不能发现异常， 诊断成像中常见的错误类别， 被医学界认为是最严重的。 许多 这些错误被归因于“搜索满意度”， 当发现另一个病变而未报告时发生 异常满足了搜索的目标。 绝大多数 减少误差技术研究和临床奋进 集中在改善图像质量，使异常， 更明显。 另一种方法是研究，从而提高， 解释过程本身。 翻译是最关键的，然而 让我们了解诊断过程的一部分。 我们是一 世界上很少有实验室追求减少检测的目标， 通过更好地理解潜在的知觉错误 涉及的过程。 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 搜索满意度（SOS）错误，并测试是否系统 自我推销可以减少这种错误。 研究 方法学将包括受试者工作特征（ROC） 曲线分析、眼睛位置记录和其他心理物理学 方法.从这些研究中获得的理解可能会导致 减少SOS错误。 这种错误的减少可能是最 随着非放射科医师对图像解释的增加， 谁，主要是由他们的临床怀疑驱动， 易受包括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.
