摘要
目的评价定量CT(QCT)骨密度测量在诊断老年男性骨质疏松症中的应用价值。方法收集我院同时接受腰椎DXA、髋关节DXA和腰椎QCT检查、年龄>60岁的男性受检者314例。比较DXA和QCT对骨质疏松症检出率的差异。结果 DXA(腰椎正位、髋关节)对老年男性骨质疏松的检出率(35/314,11.15%)低于腰椎QCT对老年男性骨质疏松的检出率(141/314,44.90%;χ2=88.70,P<0.05)。结论腰椎QCT BMD测量对中国老年男性人群骨质疏松症的早期诊断具有重要作用。
Objective To evaluate the value of bone mineral density（BMD）measurements by quantitative computed tomography（QCT）in diagnosis of osteoporosis for the elderly men.Methods Totally 314 male subjects older than 60 years underwent both QCT and dual energy X-ray absorptiometry（DXA）.The differences between the detect rates of DXA and QCT on osteoporosis were compared.Results The detect rate of DXA（lumbar vertebrae A-P projection,hip）on osteoporosis（35/314,11.15%）was lower than that of QCT（141/314,44.90%;χ^2=88.70,P〈0.05）.Conclusion QCT BMD measurements of lumbar vertebra plays an important role on the early diagnosis of osteoporosis in elderly Chinese men.
