Muscle tissue is strongly solicited during all the life. The structural and functional properties of the muscle can be affected by its perpetual stretches and contractile activities but also by specific muscle pathologies. Imaging techniques can determine the muscle composition and morphological properties but no quantification of the mechanical properties is recorded with such imaging techniques. Magnetic Resonance Elastography technique is capable of giving the morphological and the mechanical parameters for the same exam, allowing a complete characterization of the muscle tissue. The purpose of this study is to characterize the Vastus Medialis muscle stiffness from childhood to adulthood
