摘　　要：目的:探讨股骨头缺血坏死的MR影像诊断特点。并与X线平片及CT进行比较。方法:回顾性分析48例股骨头缺血坏死患者,对比MPI、CT及X线平片表现及阳性率。结果:48例MRI检查均发现股骨头缺血坏死病变,CT发现35例,X线平片发现29例。结论:MRI可以早期诊断股骨头缺血坏死,对早期治疗和预后具有积极意义,较CT、平片敏感,是首选检查。Objective： To summarize MRI signs in the diagnosis of the avascular necrosis of the femoral head（ ANFH ）, to compare them with X-ray and CT scan findings. Methods ：48 cases with ANFH confirmed were analyzed retrospectively. All cases were performed hy X-ray, CT scan and MRI. Results： MRI found all cases of ANFH, CT found 35 cases and X-ray found 29 cases. Conclusions： MRI could display the early stage of ANFH. MRI can provide information of early treatment as well as prediction of prognosis. MRI is superior to CT and X-ray and is the first to choose.
