摘要

目的应用超声造影技术对颈动脉粥样硬化斑块新生血管进行分析,研究其与脑梗死的相关关系。方法对47例脑梗死及31例对照组患者的颈动脉斑块进行超声造影检查,比较两组斑块的强化阳性率及强化程度分级及强化定量指标差异。结果脑梗死组斑块强化阳性率89.36%高于对照组的64.51%(P<0.05);脑梗死组斑块强化分级高于对照组(P<0.05);脑梗死组造影强化参数PI、PI/PIc、AUC、AUC/AUCc、RT高于对照组(P<0.001)。结论颈动脉斑块超声造影强化特征与脑梗死可能存在相关关系,超声造影对于颈动脉斑块新生血管的量化分析可以用于脑梗死的评估。
Objective To analysis the perfusion mode of the carotid atherosclerotic plaque by contrast-enhanced ultrasound imaging, and to determine the correlation between the plaque enhancement with cerebral infarction. Methods We used contrast-enhanced ultrasonography for the 78 cases of carotid atherosclerosis, in which 47 patients with cerebral infarction, 31 patients with non-Cerebral infarct.Differences in the positive rate of enhancement, enhancement grading and enhancement quantitative indicators of two groups were analyzed. Results Plaque enhancement was found in 42(89.36%) of 47 cerebral infarction patients and in 20(64.51%) of 31 non cerebral infarction patients(P <0.05). The enhanced intensity degree and quantitative analysis of cerebral infarction patients were higher than those of non cerebral infarction patients(P <0.05). Conclusion Contrast-enhanced ultrasonography imaging of Carotid Atherosclerotic Plaque and Perfusion Quantitive Analysis can be used in evaluation of cerebral infarction.
