Outline of Final Research Achievements

The purpose of this study is to establish a method for sorting the skeletal muscle fibers type by q-space imaging. This method can acquire microstructure information of living tissue. Based on this information, we establish a method to make the type of skeletal muscle fibers noninvasive and easy to distinguish. As a result, it became possible to analyze the displacement amount in the microstructure of the water molecule, and it was possible to acquire the microsized structural information of the living tissue. In addition, compared with stained images of skeletal muscle of mouse lower thigh, comparison with the skeletal muscle type distribution in axillary cross section image of the mice's lower leg, and comparison with muscle cell diameter, significant correlation was obtained. It was confirmed as a novel technique as a method of identifying the muscle fiber type.
