The diagnostic performance and utility of chest XR in relation to chest CT in nontraumatic respiratory emergency patients.

Background And Aim: This study aimed to determine the diagnostic performance and utility of chest radiography in relation to chest computed tomography (CT) in nontraumatic respiratory emergency patients.

Patients And Methods: Patients presenting to the emergency department with respiratory complaints due to nontraumatic pathologies and who had consecutive chest XR and chest CT assessments with an interval of fewer than 6 hours were enrolled in the study (n = 561).

Results: The two methods were determined to be consistent with moderate agreement in detecting pleural effusion (κ = 0.
