【摘要】 目的 :应用背向散射积分评价颈动脉粥样硬化 ,分析不同超声特征斑块的 IBS值和 IBS标化值(IBS% ) ,反映其病理成分。方法 :应用背向散射积分检测 91例患者 172块颈动脉斑块的 IBS值和与外膜 IBS值的百分比 ,作为标化值 IBS%。结果 :硬斑 ,扁平斑 ,软斑 ,溃疡斑之间均有显著差异 (P<0 .0 5 )。结论 :背向散射积分技术能够反映斑块的不同病理成分 ,为临床提供一个客观标准更多还原

【Abstract】 Objective:To evaluate the clinical application of integrated backscatter(IBS)in carotid atherosclerosis and analyse the pathological components and IBS value of plaques with different ultrasonic property.Methods:One hundred seventy two plaques in carotid arteries were performed IBS signal analysis with acoustic densitometry.IBS of plaques was measured and standardized by the IBS of adventitia and expressed as IBS%.Results:There are statistical intergroup differences among the hard,flat plagues (on the surface layer),soft and ulcerative plagues( P <0 05).Conclusions:IBS technology can evaluate the property of the carotid plaque and provide an objective index.更多还原
