| 摘 要： | 目的 通过分析不同回声颈动脉粥样硬化斑块造影后新生血管的血供情况,探讨超声造影技术识别易损斑块的价值.方法 收集2010年11月-2011年7月在本院住院治疗的经颈动脉彩色超声检查发现颈动脉斑块者共54例（斑块总数95个）,行超声造影检查,观察斑块内新生血管增强情况,并运用声学分析软件Qontrast4.0测量斑块的平均血容量（Average blood volume,RBV）、平均血流量（Average blood flow,RBF）.结果 （1）超声造影能发现常规彩超下遗漏的低无回声斑块,增加斑块的检出率;（2）低回声及混合回声斑块的增强比例明显高于其他类型斑块（P＜0.05）,但前两者比较差别不明显（P＞0.05）;（3）低回声及混合回声斑块的RBV、RBF明显高于其他类型斑块（P＜0.05）,但前两者比较差别不明显（P＞0.05）.结论 超声造影检查能清晰显示斑块内的新生血管,为识别易损斑块提过更丰富的临床信息.

| Abstract: | Objective To analysis the value of Contrast-Enhance UItrasonography（CEUS） in distinguish of the unstable plaques. Methods The study population included 54 patients （95 plaques total） who conformed to inclusive criteria. The CEUS were taken to each patient. Then all the data of the examinations were analyzed and compared. Results The soft plaques and mixed plaques had a significantly higher proportion of contrast-a- gent enhancement compared with hard plaques（P〈0. 05）, but no significant difference between them, that is similar to the average blood volume （RBV） and the average blood flow（RBF）. Conclusions CEUS showed to be reliable and effective in testing the neovascularization in carotid atherosclerotic plaques. |
