Objective.检查超声测量身体成分与参考技术：双能X线吸收测定法（DXA）的比较。我们评估了便携式超声设备在估计全身脂肪量与DXA评估成人的准确性。方法.使用便携式超声设备与当代参考DXA设备（Hologic Discovery A）进行比较，以估计体脂量。对人体测量数据进行了评估，以最大限度地提高与超声器械相关的软件输出。本研究开发了超声技术（US）和DXA之间的交叉验证。在83名女性和41名男性的样本中，将超声估计的全身脂肪量与DXA模型进行了比较。结果女性和男性体脂超声技术（US）与DXA的相关性均较好（r（2）= 0.97，P <0.01），估计标准误（SEE）分别为2.1kg和2.2kg。结论使用基于US的便携式设备产生了与DXA参考技术相关的非常准确的BF估计。由于DXA吸收测定技术不可互换，因此需要在更现代的DXA上重新校准我们的超声设备。
Objective. To examine measurement of body composition by ultrasound compared with a reference technique:dual energy X-ray absorptiometry (DXA). We evaluated the accuracy of a portable ultrasound-based device in estimating total body fat mass with those assessed by DXA in adult. Methods. Body fat mass has been estimated using a portable ultrasound-based device in comparison with a contemporary reference DXA apparatus: the Hologic Discovery A. Anthropometric data has been assessed in order to maximize the output of the software associated with the ultrasound-based device. A cross-validation between ultrasound technique (US) and DXA was developed in this study. Total body fat mass estimated by ultrasound was compared with this DXA model in a sample of 83 women and 41 men. Results. Ultrasound technique (US) of body fat (BF) was better correlated with DXA in both women (r (2) = 0.97, P < 0.01) and men (r (2) = 0.92, P < 0.01) with standard errors of estimates (SEE) being 2.1kg and 2.2kg, respectively. Conclusion. The use of a portable device based on a US produced a very accurate BF estimate in relation to DXA reference technique. As DXA absorptiometry techniques are not interchangeable, the use of our ultrasound-based device needs to be recalibrated on a more contemporary DXA.
