| Outline of Final Research Achievements |
The main result of our study was to evaluate the microanatomy of the skeletal muscle using diffusion tensor imaging (DTI). We clarified the morphology of the skeletal muscle cell by using eigenvectors calculated by DTI. And also we clarified the existance of another diffusion restricting factors except for the membrane of the skeletal muscle cell. Moreover, we could succesfully generate the fiber tractography of the skeletal muscle by also using DTI. We also clarified the factors of failure of generating fiber tractography.
As for the lipid metaboolism of the skeletal muscle measured by MR spectroscopy, we clarified several factors including diabetis and subject's age could also affect the successful measurement of lipid metabolism of the skeletal muscle.
