3D lung motion assessments on inspiratory/expiratory thin-section CT: Capability for pulmonary functional loss of smoking-related COPD in comparison with lung destruction and air trapping

Highlights • Craniocaudal-axis motions have significant correlations with functional lung volume. • Ventrodorsal-axis motion has significant correlations with pulmonary function test. • Lung motion parameters have closing relationships with clinical COPD stages.
