Development of new MR Elastography pulse sequence

本研究的目的是改进和评价新型MR弹性成像：MRE（即使用磁共振成像组织弹性的技术）。找到了磁共振成像的薄弱环节。并对其脉冲序列系统进行了改进。用改进的脉冲序列评价下段骨骼肌的特性。作为内容，通过弹性评价骨骼肌运动功能和各向异性。

The aim of this study is to improvement and evaluation of novel MR Elastography : MRE (i.e. technique for imaging as for the elasticity of the organization using magnetic resonance). We found the weak point of MRE imaging. And, its pulse sequence system has been improved. The characteristic of the lower skeletal muscle was evaluated by the improved pulse sequence. As content, the skeletal muscle motor function and anisotropy was evaluated by elasticity.
