Difference in the Craniocaudal Gradient of the Maximum Pixel Value Change Rate between Chronic Obstructive Pulmonary Disease Patients and Normal Subjects Using Sub-mGy Dynamic Chest Radiography with a Flat Panel Detector System

Difference in the Craniocaudal Gradient of the Maximum Pixel Value Change Rate between Chronic Obstructive Pulmonary Disease Patients and Normal Subjects Using Sub-mGy Dynamic Chest Radiography with a Flat Panel Detector System

Highlights • 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.
