骨样骨瘤的CT与X射线诊断效果比较

Comparisons of the efficacy between CT and X-ray analysis for the diagnosis of osteoid osteomas

目的：对比分析骨样骨瘤患者的CT与X射线诊断效果。方法收集中航工业三六三医院2005年3月至2012年5月放射科与骨科收治的骨样骨瘤患者的临床病历资料，共92例。其中CT扫描检查组34例，X射线扫描检查组58例。结果患者骨样骨瘤病灶大小多在1．0～1．5cm；CT扫描的敏感性明显高于X射线扫描检查（χ2＝8．23，P＝0．007）；CT扫描诊断瘤巢骨质钙化准确率明显高于X射线扫描检查（94．1％vs．86．2％；χ2＝6．85，P＝0．024）。结论CT扫描可辅助诊断不常见部位的骨样骨瘤，其敏感性明显高于X射线扫描检查。

Objective To compare the efficacy of CT and X-ray analysis in the diagnosis of osteoid osteomas （OOs） .Methods Clinical data of 92 OOs patients ,admitted to 363 Hospital of Chengdu City during March 2005 and May 2012 ,were retrospectively analyzed .In all patients ,34 cases received CT evaluation ,and 58 received X-ray evalu-ation .Results The diameters of most of the OOs ranged from 1 .0 cm to 1 .5 cm .It was significantly more sensitivity in the diagnosis of uncommon OOs in CT evaluation group than X-ray evaluation group （χ2 =8 .23 ,P=0 .007） ,the same as the accuracy in the diagnosis of bone calcification （94 .1% vs . 86 .2% ,χ2 = 6 .85 ,P = 0 .024 ） . Conclusion More sensitivity could be able to attained in the diagnosis of uncommon OOs and bone calcification by CT evaluation than X-ray evaluation .
