OBJECTIVE.本文的目的是使用低辐射剂量（定义为7-15 mGy x cm的剂量长度乘积）的MDCT血管造影，对主动脉弓的正常解剖结构和先天性主动脉弓异常的最常见变异进行综述。放射科医生应准备充分描述先天性主动脉弓异常;在CT血管造影上识别它们，特别是血管环或异常动脉的存在或不存在;并解释它们与气管和食管的关系。
OBJECTIVE. The purpose of this article is to review the normal anatomy of the aortic arch and the most common variations of congenital aortic arch anomalies using low-radiation-dose, defined as a dose-length product of 7-15 mGy x cm, MDCT angiography.CONCLUSION. Radiologists should be prepared to fully describe congenital aortic arch anomalies; recognize them on CT angiography, especially the presence or absence of vascular rings or aberrant arteries; and explain their association with the trachea and esophagus.
