Value of dual-energy x-ray absorptiometry as a diagnostic and assessment tool in early rheumatoid arthritis

Rheum Dis Clin North Am. 2005 Nov;31(4):715-28. doi: 10.1016/j.rdc.2005.07.013.


New research has revealed common pathophysiologic and cellular mechanisms behind the development of osteoporosis and joint damage in rheumatoid arthritis (RA). Because osteoporosis is a direct consequence of the inflammatory disease process, bone mass measurements in principle could be an outcome marker of inflammation, of damage, and of response to therapeutic intervention. Several devices have been developed for quantitative bone mass assessment including dual energy x-ray absorptiometry (DXA), which is considered the reference standard. This article based on current data and understanding discusses the use of DXA as a diagnostic and assessment tool especially in early RA.
