Research Abstract

It is very rare to perform skeletal muscle MRI in the daily practice. However, we applied diffusion tensor imaging (DTI), which was new imaging technique, to the skeletal muscle, and we could make it possible to depict skeletal muscle fiber. In addition, we could grasp the microanatomy of the skeletal muscle by DTI.
Moreover, we could also realize to measure the lipid metabolism at the skeletal muscle using MR spectroscopy.
We have presented these several research results in the conference held in Japan, or the other international meetings. And also we presented it by three research papers during research period.
