摘要
目的：测量我国正常成人骨密度值，为老年骨质疏松症的诊断提供依据。方法：使用ＱＣＴ体模对１００例健康者进行骨密度ＣＴ测量。结果：正常成人骨密度与年龄明显相关，其骨密度值以２１～３０ 岁最高，男性１７０ｍｇ／ｃｍ，女性１８０．６ ｍｇ／ｃｍ ，女性骨密度高于男性，４１～５０ 岁后男性高于女性，５１～６０ 岁女性骨密度４０％ 低于骨折阈值（１００～１１０ ｍｇ／ｃｍ） ，而６１～７０ 岁女性低于骨折阈值者占７０％ ，男性则在６１～７０ 岁始有低于骨折阈值者占３０％ 。结论：我国老年男女。
Objective:The values one mineral density was measured in normal individuals.Provided diagniosis thereunder with osteoporosis.Methods:Bone mineral density was measured in 100 normal individuals using QCT phantom.Results:The results was showed obvious age correlation.The hightest values of bone mineral density are in the 21～30 age_group with 170 mg/cm in men and 180.6 mg/cm in women.The values of bone mineral density in women is highter in man.The values in man is highter in women after 41～50 age_group.The values of bone mineral density is low fracture threshold(100～110 mg/cm) in 40% women in the 51～60 age_group and in 70% women in the 61～70 age_group.The values of bone mineral density is low fracture threshold in 30% men in the 61～70 age_group.Conclusion:The agedness in China,especially women suffer from osteoporosis at large.
