Abstract: 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 select-ed. These literatures in diagnosing ANFH with CT and MR imaging were analysed with Meta-analysis 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.
