摘　　要：目的:探讨实时超声造影(contrast-enhanced ultrasound,CEUS)技术评估颈动脉斑块稳定性的价值。方法:以颈动脉斑块患者为研究对象,对其不同回声强度的斑块进行CEUS技术检查,观察斑块内新生血管的增强程度及增强特征。结果:低回声或混合性回声斑块内新生血管较等回声或高回声斑块内新生血管增多,且晚期增强程度明显增强,差异有统计学意义(P<0.05)。从肩部向中心增强的斑块明显多于从基底部向中心增强的斑块。结论:斑块内新生血管的增强程度及增强特征能更好地评估斑块的稳定性,进而预测脑卒中的风险。Objective: To explore the value of real-time contrast-enhanced ultrasound (CEUS) in evaluating the stability of ca- rotid artery plaques. Methods: In this study, carotid artery plaques with di erent echo intensity were examined by CEUS to observe the enhancement degree and characteristics of new blood vessels in the plaques. Results: Neovascularization in hypoechoic or mixed echo plaques was higher than that in isoechoic or hyperechoic plaques, and the degree of late enhancement was signi cantly en- hanced, with statistically signi cant di erences (P<0.05). There were signi cantly more shoulder-to-center enhancement than base- to-center enhancement. Conclusion: The enhancement degree and enhancement characteristics of new blood vessels in the plaques can better evaluate the stability of the plaques and thus predict the risk of stroke.
