摘　　要：目的 :探讨股骨头缺血坏死的磁共振诊断。方法 :对 6 0例经磁共振诊断为股骨头缺血坏死的MRI图像进行观察与分析 ,并与临床症状比较。结果 :MRI能较特异地反映股骨头缺血坏死的各期表现 ,“双线征”是股骨头缺血坏死早期的特征表现。结论 :MRI不仅能发现股骨头缺血坏死的早期病变 ,且能反映病变的确切范围和程度 。Objective To evaluate the diagnosis value of MRI i n avascular necrosis of femoral head(ANFH).Method 60 cases of avasc ular necrosis of femoral head were studied with MRI,compared the findings with c linical symptoms.Results MRI could specifically reflect the each stage imaging findings of avascular necrosis of femoral head.'Double-line sign 'is the characteristic expression of MRI in early avascular necrosis of femoral head.Conclusion MRI could exactly display early ANFH and reflect the exact range.It is very valuable in early treatment and prognosis.
