What is the difference between lung function and chest X-ray?

Both lung function and chest X-ray can be used to check the lungs, which is a routine examination item of health examination. But many customers don't know the difference between the two, and they don't know which is more accurate. In this regard, Hefei Ainuo physical examination experts introduced as follows: First, lung function examination: it has important guiding significance for early detection of lung and airway lesions, assessment of the severity of the disease, diagnosis of lesion sites and so on. And there is no harm to the body, no pain and discomfort. It also has the advantages of high sensitivity, easy repeated detection and easy acceptance by patients, and is an important examination method for respiratory diseases. Followed by chest X-ray examination: chest X-ray is often used to examine the chest, including ribs, thoracic vertebrae and soft tissues. There are also diseases such as chest, lung tissue, mediastinum and heart. Such as pneumonia, tumor, fracture, pneumothorax, cor pulmonale and heart disease. X-ray chest film can clearly record the general lung lesions, such as lung inflammation, mass, tuberculosis and so on. X-ray films can observe the lesions in parts with little difference in thickness and density by using the different densities of human tissues. Compared with chest fluoroscopy, X-ray chest film is clearer and can find subtle lesions. The two examinations are not only different in content, but also different in examination methods, but they are both effective examination methods for the lungs. The combination of the two tests can accurately evaluate the health status of the lungs. Therefore, only two items can be done during physical examination, and only one item can not effectively evaluate lung health.
