摘　　要：目的评价CT和MRI对股骨头缺血坏死（ANFH）的诊断效果。方法通过检索收集近10年来国内外公开发表的关于股骨头缺血坏死的CT和MRI诊断的文献，按照一定的纳入标准进行筛选，对符合标准的21篇文献在诊断ANFH方面使用软件StataSE10．1进行Meta分析。结果MRI对股骨头缺血坏死的诊断价值高于CT，两者差别有统计学意义[OR=0．13（95％CI，0．03～0．51）]。结论MRI是首选的股骨头缺血坏死诊断方法。Objective To evaluate the value of computed tomography（CT） and magnetic resonance imaging（MRI） in diagnosis of avascular necrosis of the femoral head（ANFH）. Methods The literatures of ANFH diagnosed with CT and MR imaging published in the last ten years were collected by searching. Of that,21 literatures were correspond for the standards in this study and were selected. These literatures in diagnosing ANFH with CT and MR imaging were analysed with Metaanalysis by the sofeware of StataSE10. 1. Results MRI was more effective than CT in diagnosing ANFH. There was significantly different in statistics between them [OR= 0.13,95 % CI（0.03 -0.51）]. Conclusion In comparison with CT, MRI is the better method in diagnosing ANFH.
