摘要
弹性成像作为一种重要的组织定征手段在过去20年里成为研究热点。传统的静态/准静态弹性成像难以从体外对体内通过机械方法进行有效施压,近年来研究者专注于新的远程"触诊"手段,即声辐射力弹性成像。本文对三种主要声辐射力弹性成像方法,即谐波运动成像、脉冲声辐射力成像和剪切波弹性成像的研究进行综述。
Elastography has been a hot spot in the last 20 years as an important research modality of tissue characterization.Traditional static/quasi static-elastography is restricted by the effectiveness of ex vivo mechanical ＂palpation＂.In recent years,researchers have focused on the new way of remote ＂palpation＂,i.e.acoustic radiation force elastography.The research on three major modalities including harmonic motion imaging,acoustic radiation force impulse imaging and super shear imaging were reviewed,and the comparison among them were made in this paper.
