Dual energy X-Ray absorptiometry body composition reference values from NHANES. [PDF]

PLoS ONE, 2009
In 2008 the National Center for Health Statistics released a dual energy x-ray absorptiometry (DXA) whole body dataset from the NHANES population-based sample acquired with modern fan beam scanners in 15 counties across the United States from 1999 ...

Dual-Energy X-Ray Absorptiometry [PDF]

North Carolina Medical Journal, 2014
Assessment of bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) plays a vital role in the diagnosis of osteoporosis and in monitoring a patient's response to drug therapy. This commentary will discuss controversies surrounding the use of DXA for screening and monitoring of BMD in women.

Dual energy X‐ray absorptiometry: gold standard for muscle mass?

Journal of Cachexia, Sarcopenia and Muscle, 2018
Since the late 90s, dual energy X-ray absorptiometry (DXA) has been validated against so-called gold standards for body composition (BC) by comparison to chemical analysis, dissection, and anatomy-based imaging methods (CT or MRI).
