PRECISION ASSESSMENT OF DXA

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。列出的机构是 研究中心，而研究中心不一定是研究者所在的机构。 本研究的目的是评估GCRC支持的研究中使用的DXA技术人员的骨矿物质密度和全身脂肪百分比的精密度（当某人在同一次访视期间扫描两次时，将获得相似的测量值）。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The purpose of this study is to assess the precision (similar measurements will be obtained when someone is scanned twice during the same visit) of bone mineral density and total body fat percentage of the DXA technicians utilized in GCRC-supported studies.
