摘要
目的:研究绝经后骨质疏松症骨密度T值与腰椎Cr值的相关性。方法:采用双能骨密度公对124例绝经2年以上的妇女进行检测,根据检测结果分组,其中骨质疏松症67例(A组),骨量减少者32例(B组),正常者25例(C组),并检测其k椎体横断面骨皮质和松质的CT值,统计分析各组骨密度T值与腰椎体CT值的相关性。结果:各组骨皮质和骨松质cr值分别为287.82±96.35、296.06±92.14、316.34±81.18和5.72±35.64、99.76±23.10、189.09±37.03,各组间骨皮质CT值比较差异无统计学意义(P>0.05),而骨松质CT值比较,差异有统计学意义(P<0.05);各组间骨密度T值和L3椎体骨皮质CT值无相关性(r=0.019,t=0.151,P>0.05),和骨松质CT值存在相关性(r=0.914,t=18.127,P<0.05)。结论:检测腰椎体骨松质Cr值对绝经后骨质疏松症的诊断有参考价值,而检测腾椎体骨皮质的CT值无参考价值。
OBJECTIVE ： To investigate the dependablity of T value in bone mineral density and CT values on body of lumber vertebre in patients with postmenopausal osteoporosis, nethods：124 cases of women with menopause above 2 years were choosed for the expriment and checked by double - energy bone density machine. They were divided by detection results into three groups, group A （ osteoporosis, 67 cases）, group B （ osteopenia, 32 cases） and group C （ normal, 25 cases ）. T values of cortical bone and spongiosa in the cross section of 13 centrum for all were measured, and then in three groups the dependablity of T value in bone mineral density and CT values on body of lumber vertebre were analyzed statistically. Results： T values of cortical bone and spongiosa in three groups were respectively 287.82 ± 96.35, 296.06 ± 92.14,316.34 ± 81.18,5.72 ± 35.64 and 99.76 ± 23.10,189.09 ± 37.03. There had no statistical significance on T values of cortical bone（ P 〉 0.05 ） in three groups, but had on T values of spongiosa（ P 〈 0.05 ）. There had no dependablity of T value in bone mineral density and CT values on cortical bone of 13 c entrum （r = 0. 019, t = 0.151, P 〉 0.05 ）, but had on that with CT values of spongiosa（ r = 0. 914, t = 18. 127,P 〈 0.05 ）. Conclusion：The detection on CT values of spongiosa in body of lumber vertebre had reference value for diagnosis of postmenopausal osteoporosis, but had not to that of cortical bone.
