Abstract:
Objective: To explore the value of evaluation of the diaphragmatic motion in chronic obstructive pulmonary disease (COPD) patients with dynamic X-ray chest radiography under calm breathing. Methods: Dynamic X-ray chest radiographs were performed in 96 COPD patients (COPD group) and 50 healthy controls (control group) under calm breathing. The range, speed and time of the diaphragmtic motion were obtained and analyzed. Results of lung function tests of 2 groups were recorded. Dynamic X-ray chest radiographs and pulmonary function parameters were compared between 2 groups, and the correlations of diaphragmatic motion parameters and lung function parameters were analyzed, respectively. Results: The left and right side diaphragmatic motion amplitude in COPD group ([18.63±7.45]mm, [15.64±5.98]mm) were larger than those in control group ([14.69±5.40]mm, [13.13±4.84]mm, both P<0.05). During inspiratory phase and expiratory phase, the motion speeds of left diaphragm in COPD group were 18.79 (15.67, 22.67) mm/s and 16.00 (12.36, 21.23) mm/s, the right side were 17.00 (12.71, 19.73) mm/s and 13.75 (9.50, 16.83) mm/s, respectively, while in control group of the left side were 15.33 (13.96, 17.71) mm/s and 11.42 (9.63, 16.00) mm/s, of the right side were (14.91±4.38) mm/s and (10.66±3.66) mm/s, respectively (all P<0.05). There were statistical differences of lung function between 2 groups (all P<0.01), but the pulmonary function parameters were not significantly correlated with dynamic chest radiograph examination parameters in COPD group (all P>0.05). Conclusion: Using dynamic X-ray chest radiograph could quantitatively analyze the diaphragmatic movement of COPD patients, providing a new examination method for accurate clinical evaluation of COPD.
