DXA measurements of fat and bone mineral density in relation to depth and adiposity.
Significant effects of depth and adiposity on measurements of fat have been observed, which if also true in-vivo, have important implications for studies at the extremes of body composition, or for longitudinal measurements in subjects who show large changes in tissue thickness. Measurements of BMD under similar circumstances appear to be more robust. However, assessments of the absolute accuracy of DXA measurements await comparison with chemical analysis of human or animal cadavers.
