多层螺旋CT血管造影在颈动脉粥样硬化中的应用

颅外颈动脉粥样硬化是缺血性卒中的重要原因.颈动脉粥样硬化斑块向管腔内隆起引起管腔狭窄或斑块脱落,造成远端血管栓塞,从而导致脑部供血减少而发生缺血性事件.多层螺旋CT的容积数据采集能提供高质量的二维和三维图像,其成像技术已成为一种非常有效的颈动脉粥样硬化检测工具.文章对颈动脉粥样硬化多层螺旋CT血管造影的诊断应用和缺陷进行了综述.

Application of Muitislice Spiral CT Angiography in Carotid Atherosclerosis

Extracranial carotid athcrosclcrosis is the major cause of ischcmic stroke.The intumescence of carotid atherosclerotic plaque in meries results in lumen stenosis or detachment of plaque organisms.causing the distal vascular embolization,and thus resulting in a reduced cerebral blood supply and cerebral ischemic event.The volume data acquisition of multislice spiral CT angiography can provide high-quality two-dimensional and three-dimensional images,its imaging technique has become a very effective detection tool for carotid atherosclerosis.This article reviews the diagnosis application of multislice spiral CT angiograohy of carotid atherosclerosis and its pitfalls.
