Study The Value of Acoustic Radiation Pulse (ARFI) Imaging In Assessing Cervical Vascular Plaque

目的:对声辐射力脉冲(ARFI)成像技术在评估颈部血管斑块的价值进行分析。方法:回顾性分析2013年6月-2016年6月于本院医治的缺血性脑卒中患者114例为研究组,同期选取于我院检查的健康人群104例为对照组。两组均予以ARFI成像技术检查,测量记录斑块剪切波传播速度(SWV),观察两组斑块检出率,各类型斑块SWV均值,两组各类型斑块分布情况。结果:研究组共114人,检出有斑块的79例,共检出163个斑块,其中强回声36个、低回声51个、等回声31个、混合回声45个;对照组共104人,检出有斑块的28例,共检出59个斑块,其中强回声19个、低回声16个、等回声10个、混合回声14个;研究组斑块检出率为69.29%,对照组斑块检出率为26.92%,两组斑块检出率比较差异具统计学意义(P<0.05);强回声、低回声、等回声及混合回声SWV均值两两间比较具可比性(P<0.05)。结论:ARFI成像技术对颈部血管斑块具较高评估价值,提高斑块检出率,可作为诊断颈部血管斑块的理想手段。

Objective：To evaluate the value of acoustic radiation pulse（ ARFI） imaging in assessing cervical vascular plaque.Methods：A total of 114 patients with ischemic stroke admitted to our hospital from June 2013 to June 2016 were retrospectively analyzed,and 104 healthy subjects selected from our hospital during the same period were selected as the control group.Both groups were examined by ARFI imaging technique.The ARFI imaging was used in both groups to measure the velocity of shear wave propagation（ SWV）,then observed the plaque detection rate of the two groups,the average SWV of each type of plaque,and the distribution of two types of plaques.Results：In study group（ 114 patients）,79 plaques were detected and 163 plaques were detected,including 36 with strong echoes,51 with low echoes,31 with equal echoes and 45 with mixed echoes.In the control group（ 104 patients）,twenty-eight plaques were detected,59 plaques were detected,including 19 with strong echoes,16 with low echoes,10 with equal echoes and 14 with mixed echoes.The detection rate of plaque was 69.29% in the study group and 26.92% in the control group.The difference of the detection rate of the two groups was statistically significant（ P〈0.05）.The strong echo,low echo,equal echo and mixed echo SWV mean comparable between the two groups（ P〈0.05）.Conclusion：The ARFI imaging technique has high evaluation value on cervical vascular plaque and improves the detection rate of plaque,which could be used as an ideal method to diagnose cervical vascular plaque.
