Abstract
Dual energy x-ray absorptiometry (DXA), which is the result of further development of dual photon absorptiometry (DPA), was, as DPA, originally developed for measurement of bone mineral. Recent studies indicate that DXA also can measure body composition. We have previously shown a good in vitro accuracy of body composition measurements by DXA1. Comparison of body composition measurements in vivo by DXA with established methods showed a high correlation (r = 0.9), but a lack of agreement was indicated1. Because most methods of measuring body composition are indirect (in the sense that they rely on physical properties or chemical constants, derived from a very limited number of analyses of human cadavers2–4), the “true” accuracy of body composition measurements in vivo by DXA (as well as by the other methods) is at present unknown.
