摘要

目的探讨使用两台不同定量超声骨密度仪检测跟骨骨密度所得结果的相关关系。方法随机选取479名成年女性作为检测对象，应用美国GE公司生产的Achilles Express定量超声骨密度仪（AE）和韩国OsteoSys 公司生产的SONOST 3000定量超声骨密度仪（SN）同时测定其右侧跟骨的骨密度，对所得的结果进行比较分析。结果（1）测量结果比较：AE检测出的T值和骨硬度指数（SI）均高于SN所测得的结果并具有组间差异（P<001）;（2）测量结果的相关性：两台定量超声骨密度仪所测得的T值和SI均有显著的正相关（P<0.01），并且有显著的线性相关（P<0.01），线性回归方程分别为：TSN=0.533*TAE -1.661，SISN=0.605*SIAE-5.493。（3）AE和SN两台仪器对骨质疏松的检出率分别为3.8%和17.7%，差异有显著的统计学意义（P<0.01），但测定结果亦具有一致性并有统计学意义（P<0.01）。结论 AE和SN两台定量超声骨密度仪的检测结果存在相关关系，但也有明显差异。因此，为了准确的评价超声骨密度仪在骨质疏松症的诊断、预防和筛查中的作用，应以国际公认的金标准“双能X线”检测结果为依据，对具有代表性且应用较为广泛的仪器的检测结果进行数据转化，以达到数据校准的目的。

Abstract

Objective To investigate the correlation between the calcaneus bone mineral densities measured by two different quantitative ultrasound bone densitometries. Methods A total of 479 female adult were randomly selected from Guangxi. Achilles Express (AE)quantitative ultrasound bone densitometry（USA）and SONOST 3000 (SN) (Korea) were used to measure calcaneus bone mineral densities the right side. Results (1)Comparison of measurement results:Tf score and stiffness index (SI) measured by AE were higher SN (P<0.01). (2)Correlation of measurement results: T score and SI measured by two quantitative ultrasound bone densitometries were significant positive linear correlated (P<0.01),the linear regression equations were: TSN=0.533*TAE -1.661，SISN=0.605*SIAE-5.493. (3)The rates of osteoporosis detected by AE and SN were 3.8% and 17.7%，respectively.The results were consistent and statistically significant (P<0.01),but they also had statistical differences(P<0.01). Conclusion There is correlation between the results measured by AE and SN. However, there are also significant differences.Therefore,the results measured by the representative and widely used instruments need to be transformed according to internationally gold standard “dual energy X-ray” in order to accurately evaluate the effect of ultrasound bone densitometry in diagnosing, preventing and screening osteoporosis,and to achieve the purpose of data calibration.
