OBJECTIVE
To assess interobserver agreement between thoracic radiologists, radiology residents, and emergency physicians in diagnosing pulmonary embolism (PE).
MATERIALS AND METHODS
Emergency physicians, radiology residents, and thoracic radiologists evaluated 123 computed tomography pulmonary angiography images. Interobserver agreement was analysed using kappa statistics.
RESULTS
Very good agreements were observed between thoracic radiologists and radiology residents (0.81 and 0.82). Fair and moderate agreements (0.39 and 0.42) were demonstrated between emergency physicians and thoracic radiologists.
CONCLUSIONS
Important differences in interobserver agreement were found, with emergency physicians tending to overdiagnose PE.
目的
评估胸科放射科医生、放射科住院医师和急诊科医生在诊断肺栓塞（PE）方面的观察者间一致性。
材料与方法
急诊科医生、放射科住院医师和胸科放射科医生对123例计算机断层扫描肺血管造影图像进行评估。使用kappa统计分析观察者间一致性。
结果
胸科放射科医生与放射科住院医师之间观察到非常好的一致性（分别为0.81和0.82）。急诊科医生与胸科放射科医生之间表现出一般和中等程度的一致性（分别为0.39和0.42）。
结论
发现观察者间一致性存在重要差异，急诊科医生倾向于过度诊断肺栓塞。
