摘　　要：目的:分析超声多模态成像评价颈动脉斑块易损性的价值。方法:选取2021年10月~2022年10月本院收治的80例疑似缺血性脑血管病患者,全部患者均接受常规超声检查、超声增强造影检查及剪切波弹性成像检查,对斑块杨氏模量值进行测量,对斑块强化程度进行评估,按照二维超声及超声增强表现对斑块风险等级进行评估。结果:全部80例患者中,颈动脉常规二维超声共检出斑块100个,46个低回声斑块,17个强回声斑块,37个混合斑块。低回声斑块、强回声斑块、混合斑块的YM值比较差异有统计学意义(P<0.05)。超声造影的强化程度能对斑块内新生血管进行显示,其中14个斑块为Ⅰ级,20个斑块为Ⅱ级,23个斑块为Ⅲ级,43个斑块为Ⅳ级;不同强化斑块的YM值比较差异有统计学意义(P<0.05)。全部100个斑块中,32个为低风险斑块,68个为高风险斑块;高风险斑块的YM值显著低于低风险斑块,差异有统计学意义(P<0.05)。结论:常规超声检查、超声对比增强检查及剪切波弹性成像检查,具有高效、便捷等特点,能对斑块内的新生血管数量进行准确反映,对斑块的风险等级、稳定程度进行评估,能为判断斑块易损性提供准确和客观的信息,能对颈动脉斑块进行全面评估,并对心血管疾病的发生风险进行预测。Objective:Analyze the value of ultrasound multimodal imaging in evaluating the vulnerability of carotid artery plaques.Methods:80 patients with suspected ischemic cerebrovascular disease were selected,all of whom were admitted to our hospital from October 2021 to October 2022.All patients underwent routine ultrasound examination,contrast-enhanced ultrasound examination,and shear wave elastography.The Young’s modulus value of the plaque was measured,and the degree of plaque enhancement was evaluated.The risk level of the plaque was evaluated based on two-dimensional ultrasound and ultrasound enhanced performance.Results:Among all 80 patients,a total of 100 plaques,46 hypoechoic plaques,17 hyperechoic plaques,and 37 mixed plaques were detected by conventional two-dimensional ultrasound of the carotid artery.There was a statistically significant difference in YM values among low echo plaques,strong echo plaques,and mixed plaques(P<0.05).The degree of enhancement of contrast-enhanced ultrasound can display neovascularization within plaques,with 14 plaques being grade I,20 plaques being grade II,23 plaques being grade III,and 43 plaques being grade IV;There was a statistically significant difference in the YM values of different enhanced plaques(P<0.05).Among all 100 plaques,32 are low-risk plaques and 68 are high-risk plaques;The YM value of highrisk plaques was significantly lower than that of low-risk plaques,and the difference was statistically significant(P<0.05).Conclusion:Routine ultrasound examination,contrast-enhanced ultrasound examination,and shear wave elastography examination have the characteristics of high efficiency and convenience.They can accurately reflect the number of new blood vessels in plaques,evaluate the risk level and stability of plaques,provide accurate and objective information for determining plaque vulnerability,comprehensively evaluate carotid plaques,and predict the risk of cardiovascular disease.
