Application of imaging in pulmonary function assessment

Pulmonary function test (PFT) is the most common and effective method for functional diagnosis and screening of respiratory diseases, but it is not suitable for all patients and the procedure is relatively complex. With advances in imaging technology and the application of artificial intelligence, imaging can not only circumvent the limitations of PFTs but also reconstruct images, quantify lung structure, and predict pulmonary functional responses. ​This article reviews the application of different imaging tests in pulmonary function, the measurement of pulmonary function in different diseases, and the latest advances in artificial intelligence. • This article reviews the application of different imaging tests in Pulmonary function, the measurement of pulmonary function in different diseases, and the latest advances in artificial intelligence. • According to the characteristics of different respiratory diseases, the advantages and disadvantages of different imaging techniques for measuring lung function were summarized. • The clinical application and future prospects of pulmonary function measurement by imaging techniques are discussed.
