This excerpt was created in the absence of an abstract.

In response to our publication (Gluer et al, 1990a), Wilson and colleagues (1990) proposed the adoption of a uniform terminology and corresponding abbreviation for Dual X-ray Absorptiometry (DXA).

We supported this suggestion (Gluer et al, 1990b). Since then, the number of papers on DXA has increased considerably. Still, different abbreviations (DEXA, DER, DRA, QDR and DPX) for this technique for bone densitometry are used, several of which are proprietary in origin. DXA is the upgraded version of DPA (Dual Photon Absorptiometry). The nuclear source has been replaced by an X-ray source and this improved technology has gained wide-spread acceptance and distribution.
