摘　　要：目的探讨成人早期股骨头缺血性坏死（ANFH）的X线、CT及MRI诊断价值。方法回顾性分析经临床确诊的63例75个早期股骨头缺血性坏死的X线平片、CT及MRI的诊断结果。结果75个早期ANFH中,Ⅰ期30髋;Ⅱ期45髋;早期（Ⅰ-Ⅱ期）股骨头坏死的X线平片、CT及MRI的确诊率分别是25.3%,64%及100%。结论MRI在早期诊断ANFH的敏感性和准确率方面优于CT和X线平片。Objective To investigate X-ray,CT and MRI diagnostic value of the early avascular necrosis of the femoral head （ANFH） in adult. Methods Roentgenographic,CT and MRI features of the early ANFH in 63 cases（75 hips） confirmed clinically were analysed retrospectively. Results In 75 hips with ANFH,30 were I stage and 45 were Ⅱ stage. The definitive diagnostic rates were 25.3% ,64% and 100% by roentgenography,CT and MRI, respectively. Conclusion MRI is superior to roentgenography and CT in diagnosing the early ANFH.
