| Outline of Final Research Achievements |
For sport and rehabilitation medicine, the quantitative evaluation of exercised muscle activity is essential for facilitating optimal exercise selection and designing effective exercise programs. Magnetic resonance imaging (MRI) allows the simultaneous noninvasive investigation of superficial and deep muscle activity during exercise. However, there are many problems to be solved in order to utilize mfMRI. The purpose of this study was to investigate the new techniques of muscle functional MRI (mfMRI) in order to evaluate the human muscle activity that induced exercise.
As the results, this research revealed the basis of the acquiring condition to reduce scanning time for calculating the transverse relaxation time (T2) of skeletal muscle. We showed the muscle activity of abdominal oblique muscles by mfMRI. In addition, we could also propose a method to reduce the scanning time for calculating longitudinal relaxation time (T1) of skeletal muscle using general pulse sequence.
