摘要 目的探讨腰椎骨密度与胸主动脉钙化量的关系。方法随机选取因怀疑肺部病变行胸肺CT检查的40岁以上患者116例,CT扫描胸部,检测胸主动脉钙化程度并计算钙化量,同时用QCT行腰椎骨密度检测。对胸主动脉钙化及无钙化者的腰椎骨密度进行检测,分析CT钙化量与腰椎骨密度的相关性,分别对40~44岁、45~59岁及60岁及以上患者的胸主动脉钙化量与骨密度的相关性进行分析。结果胸主动脉壁钙化发生率随年龄增长而增加(r=-0.43,P<0.01)。胸主动脉壁钙化者的腰椎松质骨密度低于无胸主动脉壁钙化者(P<0.01)。骨密度随年龄增加逐渐降低,两者呈负相关(r=-0.72,P<0.01)。45~59岁胸主动脉壁钙化者的松质骨密度低于同年龄段无胸主动脉壁钙化者(P<0.01)。胸主动脉壁钙化者的胸主动脉壁CT钙化量与腰椎松质骨密度呈负相关(r=-0.63,P<0.01)。结论胸主动脉壁钙化及钙化量能够反映骨密度的减低程度。45~59岁骨质的钙丢失与胸主动脉壁钙化关系密切。
