Multiparametric Ultrafast Ultrasound Biomarkers for Duchenne and Becker Muscular Dystrophies

The purpose of this research study is to determine the potential of a multiparametric ultrasound approach to non-invasively monitor disease progression and to serve as an objective outcome measure for future clinical trials in Duchenne and Becker Muscular Dystrophies. The investigators will compare the muscles of ambulatory or non-ambulatory boys/men with Duchenne and Becker Dystrophies with muscles of healthy age-matched individuals of the same age and monitor disease progression in those with muscular dystrophies over a 12-month year period. The ultrafast ultrasound technology used in this study allows the simultaneous assessment of muscle structure, mechanics and physiology, including stiffness, anisotropy, viscosity, intramuscular fat, muscle volume, and microvascular perfusion. The amount of muscle alteration measured will be related to performance in daily activities, such as walking and muscle strength, in order to identify sensitive and objective markers of disease progression.
