PRECISION ASSESSMENT OF DXA

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 这项研究的目的是评估在GCRC支持的研究中使用的DXA技术人员的骨密度和全身脂肪百分比的精确度(如果某人在同一次访问期间被扫描两次，将获得类似的测量结果)。

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.
