摘　　要：目的:探讨X线、CT及MR I在诊断早期股骨头缺血坏死中的价值。方法:比较28例40个早期股骨头缺血坏死X线平片、CT及MR I的表现及诊断结果。结果:X线平片、CT及MR I发现早期股骨头缺血坏死的阳性率分别为45%、85%及95%。结论:MR I诊断早期股骨头缺血坏死比CT更具敏感性,X线平片则缺乏意义。Objective： To evaluate the value of X-ray plain, CT and MRI in early avascular necrosis of femoral head. Methods： Plain film , CT and MRI examination of 40 femoral heads of 28 eases were performed. Diagnostic results of three modalities were compared. Results： The accuracy rates of X-ray film, CT and MRI for diagnosis of ANFH were 45% ,85% and 95% respectively. Conclusion： In order to diagnose of early avascular necrosis of femoral head, MRI was superior to CT in early diagnosis avascular necrosis of femoral head. X-ray plain had some limilations for showing early lesion of the disease.
