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

利用MRI扩散张量图像（diffusion tensor image， DTI）测量水分子在具有细胞结构的神经和肌肉组织中扩散的各向异性行为，实现了对微观组织结构的无创评估。在这项研究中，我们打算通过水扩散以外的其他物理性质，如组织弹性或电阻抗，来获得组织的各向异性结构。初步实验结果表明，测量鸡肉电阻抗各向异性是可行的。

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.
