超声弹性成像技术及其应用

超声弹性成像作为一种新的超声成像方法,它通过获取有关组织弹性信息进行成像,弥补了X射线、超声成像(US)、磁共振成像(MRI)、计算机断层扫描(CT)等传统医学成像模态不能直接提供组织弹性的不足,具有无创、简单、便宜、容易应用等优点,被广泛应用于临床,成为目前医学弹性成像的一个研究热点。本文介绍了弹性成像基本的原理,详细阐述了血管内超声弹性成像、超声振动声成像、超声剪切波弹性成像、瞬时弹性成像、心肌弹性成像等不同激励方式下的几种超声弹性成像的基本原理、成像方法、国内外目前的研究现状、成像优缺点等,叙述了超声弹性成像在乳腺检测、前列腺癌的检测、射频消融监测和检测、冠状动脉粥样硬化的治疗等临床应用,并总结了超声弹性成像的发展趋势。

Ultrasonic Elasticity Imaging and Its Application

Ultrasonic elasticity imaging is a new method of ultrasonic imaging which images through getting elasticity information of relational tissue,remedying shortages of X-ray,ultrasonic(US)computer section scanning(CT)and MRI. Because of the characteristics of non-invasion,simple,low cost and easy to use,it has been used in clinic and has becom a hot spot in medical elasticity imaging.The principle of elasticity imaging,some aspects of vascular elastography,vibro-acous- tography,shear wave elasticity imaging,transient elastography,myocardial dastography,the developments,advantages and disadvantages were introduced;besides,the application and the developing trend of ultrasonic elasticity imaging in detecting galactophore and prostate,inspecting and detecting of radio-melt,therapy of sclerotic spots of coronary artery were demon- strated in this article.
