国际临床骨密度测量学会 (ISCD) 骨测量标准委员会 (CSBM) 由骨密度测量技术方面的专家组成。 CSBM 最近回顾了有关交叉校准和精度评估的科学文献。在 2005 年 ISCD 立场发展会议 (PDC) 上提交了一份包含建议的报告。基于 ISCD 专家小组在会议期间对数据进行的彻底审查，ISCD 通过了以下方面的官方立场：(1) 更改或更换硬件时的交叉校准； (2) 当整个系统更换为同一或不同制造商制造的系统时的交叉校准方法； (3) 设施之间没有进行交叉校准研究或骨矿物质密度 (BMD) 比较； (4) 单个技术人员可接受的最低精度。我们在此介绍 ISCD 关于这些主题的官方立场（这些主题是 2005 年 PDC 的结果），以及相关的理由和支持证据。
The International Society for Clinical Densitometry (ISCD) Committee on Standards of Bone Measurement (CSBM) consists of experts in technical aspects of bone densitometry. The CSBM recently reviewed the scientific literature on cross-calibration and precision assessment. A report with recommendations was presented at the 2005 ISCD Position Development Conference (PDC). Based on a thorough review of the data by the ISCD Expert Panel during the conference, the ISCD adopted Official Positions with respect to (1) cross-calibration when changing or replacing hardware; (2) the approach to cross-calibration when an entire system is changed to one made by either the same or a different manufacturer; (3) when no cross-calibration study or bone mineral density (BMD) comparison is done between facilities; and (4) the minimum acceptable precision for an individual technologist. We present here the ISCD Official Positions on these topics that were established as a result of the 2005 PDC, together with the associated rationales and supportive evidence.
