磁共振弹性图
Magnetic resonance elastography
【摘要】 磁共振弹性图(magnetic resonance elastography,MRE)利用磁共振成像(MRI)技术,测量由外力引起的组织内部质点位移空间分布,以此为输入对弹性力学的逆问题进行求解,从而获得组织弹性系数的空间分布图。介绍了M RE的成像原理,综述其各种成像手段以及MRE在医学上的应用和前景。
【Abstract】 Magnetic resonance elastography(MRE) technique is to image the elasticity properties of tissues in human body by solving the inverse problem of mechanics of elasticity. The imaging theory of MRE is introduced and the varied methods of technique are reviewed especially the method of acquiring displacement data via MRI the applications of MRE and its prospect in medicine are also reviewed.
