颈动脉多普勒超声检查是一种常用的工具，用于评估颈动脉粥样硬化。它的二维灰度可用于测量内膜-中层厚度，这是动脉粥样硬化的非常好的生物标志物，可以帮助斑块表征。斑块形态与中风风险相关。斑块溃疡也被认为是未来栓塞事件风险的强预测因子之一。彩色多普勒超声和脉冲多普勒超声已被用于检测颈动脉狭窄。多普勒超声具有独特的物理特性。操作员应熟悉多普勒超声检查的物理和其他参数，以进行最佳多普勒超声检查研究。
Carotid Doppler ultrasonography is a popular tool for evaluating atherosclerosis of the carotid artery. Its two-dimensional gray scale can be used for measuring the intima-media thickness, which is very good biomarker for atherosclerosis and can aid in plaque characterization. The plaque morphology is related to the risk of stroke. The ulceration of plaque is also known as one of the strong predictors of future embolic event risk. Color Doppler ultrasonography and pulse Doppler ultrasonography have been used for detecting carotid artery stenosis. Doppler ultrasonography has unique physical properties. The operator should be familiar with the physics and other parameters of Doppler ultrasonography to perform optimal Doppler ultrasonography studies.
