DXA与QCT预测骨折风险的进展：非骨密度测量指标

骨折风险的预测指标除了骨密度(BMD)之外还有很多进展。国际临床骨密度学会(ISCD)于2015年就DXA与QCT非BMD测量在预测骨折危险性方面的应用,包括骨小梁评分数(TBS)和髋关节几何测量的专题召开了共识研讨会。此外,定量计算机断层扫描(QCT)分析的新进展包括有限元分析、髋关节QCT、髋关节类DXA测量和随机筛查没有包含在ISCD以前的共识内。本次会上讨论的主题由ISCD理事会和科学咨询委员会提出,旨在解决临床实际需求。骨密度测量领域的国际专家小组对专题工作组提交的报告进行了审核。本文为共识研讨会会议总结。

The progress of prediction of fracture risk by DXA and QCT: non-bone mineral density indexes. Consensus of the Society of International Clinical Densitometry 2015 (originally from Journal of Clinical Densitometry, 2015; 3:274-286)

There have been many scientific advances in fracture risk prediction beyond bone mineral density (BMD). The International Society for Clinical Densitometry (ISCD) convenes a Position Development Conference (PDC) on the use of dual-energy X-ray absorptiometry beyond the measurement of BMD for fracture risk assessment, including trabecular bone score (TBS) and hip geometry measurements. Furthermore, there have been advances in the analysis of quantitative computed tomography (QCT) including finite element analysis, QCT of the hip, DXA-equivalent hip measurements, and opportunistic screening that are not included in the previous ISCD positions. The topics and questions for consideration are developed by the ISCD Board of Directors and the Scientific Advisory Committee in this meeting. They are designed to address the needs of clinical practitioners. The international expert group in the field of BMD measurement exams the report provided by the topic working group. This paper summarizes the consensus of the symposium.
