慢性气道疾病的电阻抗断层成像动态监测与评估进展OACHSSCD

Chronic airway diseases are a category of conditions characterized by chronic inflammation and structural alterations of the airways,primarily encompassing chronic obstructive pulmonary disease and bronchial asthma.China has a vast patient population with chronic airway diseases,posing significant challenges to both the public health system and economic development.The diagnosis of these diseases primarily relies on symptoms,pulmonary function tests,and imaging examinations.However,such conventional methods exhibit notable limitations in assessing regional lung function and enabling dynamic monitoring.Particularly for critically ill patients,infants,and the elderly,the difficulty in cooperating with pulmonary function tests often hinders early,precise diagnosis and treatment.Electrical impedance tomography(EIT),as an emerging functional medical imaging technology,possesses unique advantages including real-time capability,non-invasiveness,convenience,dynamic monitoring potential,and absence of radiation.It has consequently become a research hotspot in the field of quantitative assessment for chronic airway diseases.This article systematically reviews the fundamental principles of EIT technology and its application progress in chronic airway diseases,while also providing an outlook on its future research directions and clinical translation prospects.
