Electrical impedance tomography (EIT) is a new non-invasive functional imaging technology, which has the advantages of non-invasion, non-radiation, low cost, fast response, portability and visualization. In recent years, more and more studies have shown that EIT has great potential in the detection of lung diseases and has been applied to early diagnosis and treatment of some diseases. This paper introduced the basic principle of EIT, discussed the research and clinical application of EIT in the detection of acute respiratory distress syndrome, chronic obstructive pulmonary disease, pneumothorax and pulmonary embolism, and focused on the summary and introduction of indicators and functional images of EIT related to the detection of lung diseases. This review will help medical workers understand and use EIT, and promote the further development of EIT in lung diseases as well as other fields.
电阻抗断层成像（EIT）是一种新型的非侵入性功能成像技术，具有无创、无辐射、成本低、响应快、便携及可视化等优点。近年来，越来越多的研究表明，EIT在肺部疾病检测方面具有巨大潜力，并已应用于某些疾病的早期诊断和治疗。本文介绍了EIT的基本原理，探讨了EIT在急性呼吸窘迫综合征、慢性阻塞性肺疾病、气胸和肺栓塞检测中的研究及临床应用，并重点总结和介绍了与肺部疾病检测相关的EIT指标和功能图像。本综述将有助于医务工作者理解和使用EIT，并推动EIT在肺部疾病及其他领域的进一步发展。
