Quantitative ultrasound (QUS) assessment at the calcaneus has been found to be a safe and reliable method for evaluating skeletal status. In this study we have determined the normative QUS data in the Spanish population for the Sahara Clinical Sonometer (Hologic). Broadband ultrasound attenuation (BUA), speed of sound (SOS), quantitative ultrasound index (QUI) and estimated bone mineral density (BMD) were determined. We also studied the precision in vivo and in vitro. The short-term in vivo precision (CV) was 4.88% for BUA, 0.36% for SOS, 3.45% for QUI and 4.15% for BMD, while in vitro precision was 0.40% for SOS and 2.67% for BUA. Our results are comparable to reference population data previously published in other countries and may serve as reference normative data for both genders in Spain.
跟骨定量超声（QUS）评估已被证明是一种评估骨骼状况的安全可靠方法。在本研究中，我们测定了西班牙人群使用Sahara临床超声骨密度仪（Hologic）的QUS标准数据。测定了宽带超声衰减（BUA）、声速（SOS）、定量超声指数（QUI）和估算骨密度（BMD）。我们还研究了体内和体外的精密度。BUA的短期体内精密度（CV）为4.88%，SOS为0.36%，QUI为3.45%，BMD为4.15%，而体外精密度SOS为0.40%，BUA为2.67%。我们的结果与之前在其他国家发表的参考人群数据具有可比性，可作为西班牙男女的参考标准数据。
