Brief Summary:
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
Detailed Description:
The incidence and mortality of COPD continue to rise in China but the awareness level of patients with this disease is not enough Due to the low treatment compliance it is not possible to conduct regular review resulting in difficult to effectively control the disease acute aggravation of repeated attacks and then bring a heavy economic burden to society Therefore in order to reduce the occurrence of acute exacerbations and improve the quality of life of patients COPD patients need to strengthen their awareness of the disease improve treatment compliance and undergo regular review
The severity of COPD is diagnosed and assessed mainly by pulmonary function examination Lung capacity lung volume and lung diffusion capacity can be determined by a lung function test to assess the health of lung function Airflow limitation is an important diagnostic criterion and the key indicator for determining airflow limitation is the one-second rate FEV1FVC less than 07 after inhalation of bronchodilators The percentage of measured forced expiratory volume in the first second to the estimated value FEV1pred was the primary parameter for assessing the severity of COPD However some literature has pointed out that FEV1pred does not fully reflect the clinical symptoms and quality of life of patients Although pulmonary function examination is of great significance in evaluating patients lung conditions it can not fully evaluate small airway lesions and lung parenchymal injury and there are problems of non-standard and inaccurate data Due to the low rate of pulmonary function examination it can not fully represent the lung condition of patients and it is still necessary to combine other examination methods to comprehensively evaluate the lung health status of patients
Dynamic Chest Radiography DCR is a real-time X-ray imaging system that takes continuous images of a moving chest usually in 10 to 20 seconds and is a fast well-tolerated and simple chest radiography technique Measurements of diaphragm movement lung area and lung perfusion can provide multiple examination information for COPD patients and supplement baseline deficiencies in critically ill patients
The purpose of this study was to evaluate the dynamic chest radiography of COPD patients based on Chinese population analyze the characteristics of dynamic chest radiography of COPD patients and study the correlation between chest radiography and lung function To study the value of dynamic chest radiography in diagnosing COPD To investigate the role of dynamic chest radiography in evaluating the severity of airflow restriction in COPD and predicting the clinical outcome of COPD Through multidimensional dynamic assessment of patients dynamic chest radiography can help doctors more accurately diagnose patients conditions and timely interventional treatment so as to reduce the occurrence of acute exacerbations delay the risk of disease progression and improve patients quality of life
