摘要
目的 探讨超声造影在动脉粥样硬化中的诊断价值。方法 新西兰大白兔 5只 ,高脂饮食喂养 12周建立动脉粥样硬化模型。模型建立前后应用自制的脂膜氟碳声学造影剂“脂氟显”行腹主动脉超声造影。造影前后分别采用二维成像、视觉评分和视频密度法监测兔腹主动脉内膜、粥样斑超声成像特征并作定量分析。结果 造影后血管内膜、粥样斑回声明显增强 ,视频密度较造影前明显增加。结论 造影剂可提高血管内膜分辨率及粥样斑检出率 。
Objective To discuss the value of enhanced ultrasonography in monitoring atherosclerosis. Methods Five New Zealand rabbits were fed with cholesterol diet for 12 weeks in order to create the animal model of atherosclerosis. The images for abdominal aorta were obtained continuously after intravenous injection of self-made microbubbles (ZhiFuXian). The videointensity of intima and plaque were compared with those without contrast agent. Results Significant increases for intima and plaque videointensity were observed after microbubbles injection. Conclusion Enhanced ultrasonography is very effective for sonography improvement in detecting early atherosclerosis. [
