Abstract CT enhanced examination is widely used in clinical practice as a routine examination item for chest diseases, which also makes CT the main source of iatrogenic radiation. Among the commonly used CT post-processing algorithms, the iterative reconstruction algorithm can reduce the contrast agent dose and radiation dose by adjusting the scan weight, while obtaining images that meet the needs of clinical diagnosis. There is still no uniform standard for how to choose the optimal scan weight. This article mainly reviews the development process, basic principles and clinical applications of chest CT low-dose scanning combined with iterative reconstruction, in order to provide a reference for reasonable reduction of the radiation dose of CT scanning to patients and medical staff.
