摘要
目的探讨超声造影在颈动脉粥样硬化斑块稳定性评价中的应用价值。方法选取我院收治的颈动脉粥样硬化斑块进行超声造影分析。依据患者斑块回声图像特点分为软斑组、硬斑组及混合斑组,比较分析三者超声造影增强率以及包括斑块峰值强度和达峰时间等时间-强度定量分析指标。结果 61个斑块中经超声造影后有38个斑块呈现不同程度的增强,增强率达62.30%。与软斑组相比,硬斑组和混合斑组造影增强率明显下降,造影未增强率明显提高,斑块峰值强度明显降低,达峰时间明显延长,差异均具有统计学意义(P<0.05)。结论超声造影能够为颈动脉粥样硬化斑块稳定性的正确评价提供可靠依据。
Objective To probe into application value of contrast-enhanced ultrasound imaging in stability evaluation for carotid atherosclerotic plaque. Methods Selected carotid atheroselerotic plaque patients in our hospital. All the patients were made contrast-enhanced ultrasound imaging analysis. Based on the characteristics of plaque echo image, the patients were divided into soft plaque group, hard plaque group and mixed plaque group. The ultrasound contrast enhanced rates and time-intensity quantitative indicators including plaques peak intensity and peak time of patients in three groups were compared and analysis. Results After contrast-enhanced uhrasound imaging analysis, there were 38 plaques showed varying degrees of enhancement, the enhancement rate was 62.30%. Compared with soft group, hard plaque group and mixed plaque group contrast enhanced rates were decreased significantly, the contrast unreinforced rates were improve significantly, the maximum intensity were decreased significantly, the time to peak were prolonged significantly, there were statistically signifieant(P 〈 0.05). Conclusion Contrast-enhanced ultrasound imaging could provide reliable basis for the correct evaluation for the stability of carotid atherosclerotie plaque.
