Dual-energy x-ray absorptiometry (DEXA) is a safe, noninvasive, inexpensive tool for managing patients with neuromuscular diseases. Regional and whole-body DEXA can be used to guide clinical treatments, such as determining body composition to guide nutritional recommendations, as well as to monitor disease progression by assessing regional and whole-body lean tissue mass. DEXA can also be used as an outcome measure for clinical trials.
