Design outcomes

Primary

Measure	Time frame
Sensitivity for diagnosis of pulmonary contusion in measurement method of respiratory variation of permeability of 18 lung fields by chest X-ray dynamic imaging apparatus with contrast CT examination as a reference	—

Secondary

Measure	Time frame
1. Specificity for diagnosis of pulmonary contusion in measurement method of respiratory variation of permeability of 18 lung fields by chest X-ray dynamic imaging apparatus with contrast CT examination as a reference. 2. Chronological comparison of throat movable range (difference of thoracic area between inspiratory and expiratory) and variation of pixel value in inspiratory and expiratory phase with respiratory function test (%VC, FEV1.0) as references	—
