| 摘 要： | 血管内超声技术的发展提供了评价血管和斑块断面信息的手段 ,但却不能准确反映粥样斑块的生物物理属性。血管内超声弹性图通过描述血管壁径向的应变情况 ,再现了管壁和斑块的生物弹性特征 ,可以分辨不稳定斑块、预测斑块破裂并能反映斑块成分 ;结果也较之单纯血管内超声显像更为客观。我们对该项技术的构建原理和临床应用研究现状进行了综述 ,并指出了该项技术目前存在的缺点和将来的发展方向。

| Abstract: | The development of intravascular ultrasound (IVUS) techniques makes it possible to analyze the sectional information of the arteries and plaques. However, it can not precisely provide the biomechanical characterization of atheromas. The IVUS elastogram demonstrates tissue elasticity via estimating the axial stress-strain information of artery walls. With the help of such method, unstable lesions can be distinguished, the rupture inclination can be predicted, and the components of plaques are able to be classified. Compared with IVUS, elastogram is more objective. The constructing procedure and relative techniques as well as the preliminary clinical application, are reviewed in this article. The limitation at present and the probable future research direction are also mentioned. |
