| ［摘要］ 慢性颈内动脉闭塞（CICAO）是缺血性卒中的常见原因之一。随着磁共振成像（MRI）设备的不断更新及技术发展，可用的MRI序列越来越多，特别是对CICAO患者的血管斑块及脑血流动力学的评估，有更多MRI新序列可选择。但这些评估序列成像时间较长，且在具体临床应用中各有特点，扫描规范尚未形成；血管斑块及脑血流动力学的定量评估体系仍在完善。文章对近年来评估CICAO的MRI研究作一综述，以期对血管斑块和脑血流动力学评估进行归纳，为CICAO的临床诊疗提供更好的参考。 |

| Abstract: |
| ［Abstract］ Chronic internal carotid artery occlusion(CICAO) is one of the common causes of ischemic stroke. With the continuous update of magnetic resonance imaging(MRI) equipments and the development of technology, more and more MRI sequences are available, especially for the evaluation of vascular plaques and cerebral hemodynamics in patients with CICAO, more new MRI sequences are selectable. However, the imaging time of these evaluation sequences is relatively long, and they have their own characteristics in specific clinical applications. Scanning specifications have not yet been developed. Additionally, the quantitative evaluation system of vascular plaques and cerebral hemodynamics remains to be improved. This paper reviews the MRI studies on the evaluation of CICAO in recent years, aiming to summarize the evaluation of vascular plaques and cerebral hemodynamics and provide better reference for clinical diagnosis and treatment of CICAO. |
