【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Osteo Sys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(P0.01);(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(P0.01),并且有显著的线性相关(P0.01),线性回归方程分别为:T_(SN)=0.533*T_(AE)-1.661,SI_(SN)=0.605*SI_(AE)-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(P0.01),但测定结果亦具有一致性并有统计学意义(P0.01)。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 results of calcaneal bone mineral density (BMD) measured by two different quantitative ultrasound absorptiometry. Methods 479 adult women were randomly selected as subjects. Bone mineral density (BMD) of right calcaneus was measured by Achilles Express quantitative ultrasound absorptiometry (Achilles Express) produced by GE Company and SONOST 3000 quantitative Ultrasound Bone density instrument (SONOST 3000) made by Osteo Sys Company of Korea. The results were compared with those of SN, and the correlation between the results was as follows: two sets of quantitative ultrasound bone: two quantitative ultrasound bones were measured. The ratio of T value and bone hardness index was higher than that of SN, and there was a correlation between the results of the two quantitative ultrasound bone measurements (P < 0.01) and the correlation of the results between the two sets of quantitative ultrasound bones was also found in the two sets of quantitative ultrasound bone. The T value and SI measured by the densitometer have significant positive correlation (P 0.01) and significant linear correlation (P 0.01). The linear regression equations are: 1: TSNN 0. 533 T / T, 0. 605- 0. 661% sig. 0. 605AE-5.493.3AE and SN are respectively 3.8% and 17. 7, respectively. The difference is significant in the detection rate of osteoporosis between the two instruments, and the correlation between the two instruments is significant, and there is a significant difference in the detection rate of osteoporosis between the two instruments (P < 0. 05). The linear regression equation is 0. 05% and 17. 7% respectively. The linear regression equation is 0. 605% and 17. 7% respectively. The results were consistent and statistically significant. Conclusion there is a correlation between the results of AE and SN quantitative ultrasound absorptiometry. Therefore, in order to accurately evaluate the role of ultrasound absorptiometry in the diagnosis, prevention and screening of osteoporosis, we should base on the internationally accepted gold standard, "dual energy X-ray" test results, in order to evaluate accurately the role of ultrasound absorptiometry in the diagnosis, prevention and screening of osteoporosis. The test results of representative and widely used instruments are transformed to achieve the purpose of data calibration.
