| 摘 要： | 目的 观察基于双能X线吸收测量法(DXA)的三种胫骨近端软骨下骨骨密度检测方法的信度与效度。方法 招募28名健康女性,利用双能X线骨密度仪扫描膝关节;由2名研究者分别应用三种不同测量方法选取ROI进行测量分析,通过计算组内相关系数值(ICC),评价各方法的复测信度与测量者间信度,利用t检验评价区分效度。结果 三种方法均具有较好的复测信度(ICC 0.833~0.998)与测量者间信度(ICC 0.905~0.997),且对低年龄者和高年龄者具有较好的区分效度(P<0.05)。结论 利用双能X线骨密度仪研究膝关节软骨下骨具有可行性;本研究分析的三种测量方法可有选择地用于临床研究。

| Abstract: | Objective To explore the reproducibility and validity of three different dual-energy X-ray absorptiometry measurement techniques for subchondral bone mineral density (sBMD) in the knee. Methods Twenty-eight female participants were collected, and sBMD was measured using dual energy X-ray absorptiometry scans. ROI was placed in the lateral and medial compartments of tibial subchondral bone using three methods. Intraclass correlation coefficient (ICC) was calculated to describe the reproducibility. Results All three methods had excellent reproducibility (inter-observer reliability 0.905-0.997, reliability 0.833-0.998). For validity, these three methods had good discrimination validity in different age groups (P<0.05). Conclusion It is feasible of studying on knee by measuring sBMD with dual energy X-ray absorptiometry scans. Rational selection of measuring methods are necessary in clinical studies. |
