CT评估颈动脉粥样硬化的研究进展

Progresses of CT in evaluation of carotid atherosclerosis

颈动脉粥样硬化是缺血性脑卒中发生的主要危险因素之一。目前常用的影像学检查方法包括超声、DSA、CT、MRI及光学相干断层成像(OCT)等。其中,CT具有无创、快捷、空间分辨率高等优势,且近年来CT成像设备及技术发展迅速,使其在颈动脉斑块的早期诊断及随访等方面均发挥重要作用。本文对CT评估颈动脉粥样硬化的研究进展进行综述。

Carotid atherosclerosis is one of the main risk factors for cerebral vascular disease.The routine imaging examinations in clinic include ultrasound,DSA,CTA,MRI and optical coherence tomography（OCT）.Among them,CT is a noninvasive,convenient and high spatial resolution method,which can be performed rapidly and wildly in the diagnosis and follow up of carotid plaque with the recent development of CT scanner and technique.The processes of CT in evaluation of carotid plaque were reviewed in this article.
