Exploring the Diagnostic Performance of Dynamic Chest Radiology in Chronic Obstructive Pulmonary Disease

The prevalence of chronic obstructive pulmonary disease (COPD) is on the rise, leading to an increasing economic and social burden. Currently, the diagnosis and staging of COPD heavily rely on pulmonary function testing. However, limitations such as patient cooperation and comorbidities can hinder accurate diagnosis. In situations like a respiratory pandemic, pulmonary function testing may not be feasible. Dynamic chest radiography has emerged as a promising area of research due to its quick procedure, high patient cooperation, low risk, minimal radiation exposure, and reduced direct contact. Recent clinical studies have started to explore the relationship between dynamic chest X-ray measurements and lung function parameters. However, there is a noticeable scarcity of research focusing on the use of dynamic chest X-ray in aiding the diagnosis of COPD, particularly in Chinese populations where cohort data is lacking. Consequently, there is a pressing need to investigate the correlation between various dynamic chest radiograph parameters and lung function indicators, as well as their potential diagnostic value in COPD.
