Cross-Calibration of Bone Mineral Densities and Body Composition between GE Lunar Prodigy and Osteosys Primus

Background: The aim of this study was to investigate the correlation between bone mineral density (BMD) and body composition measured by Osteosys Primus® GE Lunar Prodigy® calculate conversion rate 2 devices.Methods: 40 subjects were men women in aged 20 29 years old. All participants scanned twice on both Primus (OsteoSys) Prodigy (GE Healthcare) DXA systems using manufacturers’ standard scanning positioning protocols.Results: Compared device, mean fat mass overestimated be 12.1% (1,776.9 g) whole body, 5.1% (163.9 gynoid, 6.7% (87.2 android. with BMDs underestimated 2.3% (0.023 g/cm2) 3.1% (0.035 L1-4. lean derived (1,045.3 total 3.8% (179.4 arms, 7.7% (1,104.8 legs, respectively. There a strong BMD groups.Conclusions: Linear correction equations developed ensure comparability muscle Prodigy. Importantly, use from previous studies would have increased discrepancy
