Stimulation of the quadriceps muscle group of the thigh and synchronous phase contrast imaging at a 3T MRI scanner were applied to six young and 13 elderly volunteers, to assess age-related differences. Dynamic strain and strain rate maps were reconstructed. Age-related differences both for strain and strain rate were observed and the significance of the difference increased when the vastus intermedius muscle was included.
