摘　　要：【目的】应用实时超声弹性成像评价脑卒中患者颈动脉斑块软硬度。【方法]53例脑卒中患者中以常规灰阶超声检测出低回声斑块、混合回声斑块及强回声斑块及其颈动脉狭窄，同时应用实时超声弹性成像技术计算颈动脉管壁与各种回声类型斑块的硬度比值。【结果】①常规超声可检测出低回声斑块31处、混合回声斑块37处及钙化斑块13处；②实时超声弹性图像中，低回声斑块呈黄绿色或绿色为主、混合回声斑块为蓝绿相间及强回声斑块完全呈蓝色；③低回声斑块、混合回声斑块及强回声斑块硬度比值依次增大；④颈动脉斑块硬度比值〈5．0的脑卒中患者占总体的73．4%（41／53例）。【结论】实时超声弹性成像判断颈动脉斑块硬度比值有助于评价脑卒中患者颈动脉斑块的稳定性。[Objective] To explore the real-time elastosonography for the assessment the stiffness of carotid plaques in stroke patients. [Methods] The low-echo plaques, hypoechogenicity plaques and strong-echo plaques in 53 stroke patients were found by gray scale ultrasound. Meanwhile, real-time elastosonography was used to calculate the ratio of the stiffness of carotid wall to different types of echo plaques. [Results] Thirty-one low-echo plaques, thirty-seven hypoechogenicity plaques and thirteen calcified plaques were found by routine ultrasound. Real-time elastosonography showed that the low-echo plaques were mainly yellow-green or green, and hypoechogenicity plaques were mosaic of green and blue, and the strong-echo plaques were blue. The stiffness ratio of lowecho plaques, hypoechogenicity plaques, strong-echo plaques increased by turns. The stoke patients with the stiffness ratio of carotid plaque less than 5.0 occupied 73.4% （41/53）. [Conclusion] Real-time elastosonography for calculating the stiffness ratio of carotid plaques is helpful for assessing the stability of carotid plaques in stroke pa- tients.
