摘　　要：目的探讨成人腰椎骨密度测定结果的影响因素。方法自本院2009年1月1日至2013年5月30日行骨密度检查的患者中,筛选因不同原因而重新检查或重新处理的患者,对其从操作前后结果进行比较,并对重新操作原因进行分析。结果高密度伪影、局部骨质增生都会引起BMD测定结果增高;感兴趣区调整对测定结果影响不大;信息输入及数据库的选择对BMD值没有影响,但对T值和Z值结果有影响。结论骨密度检查中,操作人员需要认真核对信息,仔细观察患者影像结果,合理处理,并且综合考虑BMD值、T值和Z值,才能保证骨密度检查结果真正反映患者病情。Objective To discuss the factors for results of bone density. Methods Retrospectively analyzed patients who were examined or processed twice in the First Affiliated Hospital of Soochow University from Jan, 2009 to May, 2013. Compared the results of two tests and analyzed the reasons of the repeated tests. Results High density artefact and hyperosteogeny increased the BMD. Region of interest made no difference on results. Information input and data base selection made no difference on BMD but effected T index and Z index. Conclusions It was important to check the information, choose reasonable data base to process and comnrehensivelv consider BMD. T index and Z index to get correct results.
