Abstract
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.
