Feasibility study to measure anisotropic physical properties of tissue by using MRI

磁共振扩散张量成像（DTI）是一种测量神经和肌肉组织中水分子扩散的各向异性行为的方法，可以实现对组织微观结构的非侵入性评价。在这项研究中，我们打算获得组织的各向异性结构的其他物理特性，而不是水的扩散，如组织的弹性或电阻抗。初步的实验结果表明，电阻抗各向异性测量鸡肉的可行性。

Noninvasive assessment of microscopic tissue structure has been realized by diffusion tensor image(DTI) of MRI that measures anisotropic behavior of water molecule diffusion in neural and muscular tissues with cell structures. In this study, we have intended to obtain anisotropic structure of tissue by other physical properties than water diffusion such as tissue elasticity or electrical impedance. Preliminary experimental results showed the feasibility to measure anisotropy of electrical impedance in chicken meat.
