| 摘 要： | 冠状动脉CT成像（CCTA）已成为一种准确率较高的评价冠状动脉解剖形态的无创手段，但是检查产生的高剂量辐射越来越受到人们的普遍关注。如何在尽可能降低辐射剂量的同时保证诊断质量已成为CCTA的研究热点。笔者就该方面近年的研究进展做一综述。

| Abstract: | Coronary computed tomography angiography(CCTA) has become a noninvasive method with high accuracy for evaluation of the coronary artery morphology, meanwhile, people have been paying more attention to the high radiation dose delivered during the imaging procedure. In recent years, it has been a hot research topic of keeping the radiation dose as low as possible with no sacrifice of the imaging quality. This article summarized and explored the advances of methods in reducing radiation dose for CCTA. |
