•Dynamic chest radiography is feasible for the evaluation of pulmonary ventilation.•It could detect physiological differences between normal subjects and COPD patients.•Craniocaudal gradients of MPCR were lower in COPD patients than normal subjects. To compare the craniocaudal gradients of the maxim...
