Reliability of 2 Different Positioning Protocols for Dual-Energy X-ray Absorptiometry Measurement of Body Composition in Healthy Adults
2016, Journal of Clinical DensitometryDual energy X-ray absorptiometry (DXA) can be used to predict live animal and whole carcass composition of sheep
2011, Small Ruminant ResearchCitation Excerpt :The sheep carcass was also scanned prone but with the front legs outstretched due to positioning of the legs after hanging. Interestingly, Lambrinoudaki et al. (1998) found that DXA derived FTM and BMC were lower while DXA-derived LTM was higher when humans were scanned in the prone rather than supine position which may explain some of the findings discussed below. Regardless, the present data suggest that live sheep can be scanned in a prone position and excellent estimates of whole body, empty body and carcass composition can be obtained regardless of the scanning grid employed, provided appropriate correction algorithms are used.
Reproducibility of dual-energy x-ray absorptiometry total and regional body composition measurements using different scanning positions and definitions of regions
2009, Metabolism: Clinical and ExperimentalCitation Excerpt :Furthermore, the software handles tissue adjacent, above, and below bone using a specific interpolation system to identify bone pixels when calculating BMD for the whole body. Lambrinoudaki et al [13] compared changes in the mean values of body composition in supine and prone positions and found differences in the observed measurement values. Furthermore, in our study, there was more variation between repeated values in supine-prone than in supine-supine measurements.

2001, Journal of Clinical DensitometryAssessing Agreement of Lateral Leg Muscle and Bone Composition Using Dual X-ray Absorptiometry
2020, Journal of Clinical DensitometryCitation Excerpt :Posthoc analyses within the current study revealed a strong correlation between leg percent fat and mean differences in (1) fat mass (r = 0.669–0.796) and (2) lean mass (r = −0.703 to −0.717) between lateral and frontal scan views. This observation suggests leg fat mass amount may affect fat distribution and tissue depth between scan views, as previously suggested (31,32). Thus, the inability to draw separate ROI lines during postscan analyses when using the Hologic Horizon A, in addition to a potential magnification effect using this fan-beam scanner, may have limited the ability to account for fat distribution differences between lateral and frontal views, thereby decreasing lateral view measurement accuracy.
