Ultrasonography is a relatively noninvasive technique that is used for screening patients with muscular dystrophy; this modality is rapidly replacing electromyography (EMG) in centers that have appropriately trained staff. Even in the early stages of MD, ultrasonography shows increased echogenicity in the affected muscles, with a corresponding reduction in the underlying bone echo. Ultrasonography has the advantage of noninvasiveness, and it is reliable for continued monitoring of the disease course over time.
