| Research Abstract |
The purpose of this study was to clarify the force generating mechanism of human skeletal muscle. For this purpose, the architecture of the entire muscle and tendon structure in vivo was measured during contraction. In this study, two newly developed methods, magnetic resonance diffusion tensor imaging and tagging snapshot imaging methods, were used and were compared with the conventional method of the B-mode ultrasonography. One of the main results was that there were several error factors in magnetic resonance diffusion tensor imaging methods; such as the blood perfusion, type of muscle fibers, and the previous activation of the muscle. These factors should not be ignored in the determination of the diffusion parameters.
