     [摘要] 目的:总结7例长管状骨非潜水性骨梗死的X线、CT表现,探讨长管状骨非潜水性骨梗死的X线、CT诊断价值。方法:7例患者均拍摄了X线平片、CT检查；2例手术活检。结果：7例长管状骨非潜水性骨梗死共累及10个部位，股骨下段4个，胫骨上段4个，胫骨下段2个。其中2个部位经手术活检病理证实。X线平片显示髓腔内不均匀性骨化，CT显示髓腔内呈地图样改变，周围环以硬化边。结论:X线平片可以满足中晚期骨梗死的诊断，CT检查可以进一步明确诊断。

    Abstract:Objective To explore the diagnosis fingings of;nondiver bone infar CT ion on plain radiography and CT,by imaging manifestation in 7 cases.Methods all of patients were examined by plain radiography and CT.two of them were confirmed by biopsy.Results Ten sites of the bone infarct in 7 patients were found,including 4 in the distal femur,4 in the proximal tibia,2 in the distal tibia.Two lesion sites in these patients were confirmed by operation and pathology.Plain radiography manifestation was inhomogeneous ossification in the intramedullary cavity.CT manifestation was “mapshaped”lesions with the surrounding sclerotic rim in the intramedullary cavity.Conclusion Plain radiography can suffice for diagnosing the bone infarCT in the middle and later stages.CTexamination can obtain more sensitive diagnosis than plain radiography. ......
