Abstract
Myotonic dystrophy is an inherited multiβsystem disease. Its pathophysiology leading to muscle malfunction and damage is not well understood. ^23^Na NMR spectroscopy was applied here for an in vivo comparative study of the calf muscles of 7 myotonic dystrophy patients at various stages of the disease and 11 healthy volunteers. Both the total sodium content, expressed as the ratio of the ^23^Na and ^1^H water signals, and the fast transverse relaxation time, T~21~, determined from the triple quantumβfiltered spectra, increased in correlation with the severity of the disease. The results demonstrate that ^23^Na NMR enables the quantitation of myotonic dystrophy progression.
