In vivo 31P magnetic resonance spectroscopy (MRS) of tender points in patients with primary fibromyalgia syndrome

Rheumatol Int. 1991;11(2):51-4. doi: 10.1007/BF00291145.


31P Magnetic Resonance-Spectroscopy was performed at the site of tender points in the trapezius muscle of patients with primary fibromyalgia syndrome. Earlier, in vitro studies have reported changes in the high energy phosphate-metabolism in biopsies taken from tender points of fibromyalgia patients. The observed alterations could not be confirmed with in vivo Magnetic Resonance-Spectroscopy.
