Synopsis

Keywords: Muscle, MuscleThe changes in T2 driven by water content, oxygenation, pH, and blood volume in tissue altered during intense physical activity provides chance to measure the muscle performance. In this study, we investigated feasibility of dynamic T2 measurement for exercise-induced thigh muscle activity using conventional fast spin-echo (FASE, Fast Advanced Spin Echo) and ultrafast spin-echo EPI (SE-EPI) with 3T MRI.
