实时超声弹性成像评价颈动脉粥样硬化斑块稳定性的价值 广西贵港市港北区人民医院 537100 【摘要】目的通过实时超声弹性成像定量参数(面积比)评估颈动脉粥样硬化斑块的稳定性,为脑梗死的预防和诊治提供新的影像学依据。方法随机选取2014年12月-2015年11月我院收治的64例脑梗死患者,在实时状态下采用常规超声对颈动脉进行检测,将获得二维图与弹性图所显示的清晰斑块进行斑块范围的勾画,并计算其面积、弹性比值。结果 64例脑梗死者中,超声于56例中检出颈动脉粥样硬化斑块60处;其中有9处低回声斑块,11处等回声斑块,18处高回声斑块以及22处混合回声斑块。低回声、混合回声、等回声与高回声斑块的弹性比值逐个增大(F=,P<)。但混合回声分别和低回声、等回声斑块之间差异均无统计学意义(P>)。结论实时超声弹性成像在颈动脉粥样硬化斑块的稳定性评估中有显著的临床价值,值得关注并推广。 【关键词】实时超声弹性成像;颈动脉粥样硬化;稳定性;评价 Evaluation of the Stability of Carotid Atherosclerotic Plaque by Real-time Ultrasound Imaging [Abstract]Objective:To evaluate carotid atherosclerotic plaque stability through real-time ultrasound imaging so as to provide a new imaging evidence for the prevention and treatment of cerebral infraction. Method:To choose 64 cases of patients with cerebral infarction admitted in our hospital from December 2014 to November 2015 and to apply conventional ultrasound to detect carotid artery in real time. Sketch the patch range of the clear plaque shown on 2D and elastic graphs and calculate its area as well as elastic ratio. Results:In 64 cases of cerebral infarction,60cases of carotid atherosclerotic plaque were detected by ultrasound in 56 cases,among which,there were 9 cases of low echo patches,11equal echo patches,18 high echo patches and 22heterogeneous echo patches;the elastic ratio of low echo ,heterogeneous echo and high echo plaque increase
