股骨头缺血坏死不同影像方法结果比较

Comparison Study of X-ray and CT and MR Imaging and ECT for Femoral Head Necrosis

目的探讨成人股骨头缺血坏死的X线、CT、MRI和ECT表现及病理基础。方法对120例疑诊FHN患者同期进行了X线、CT、MRI和ECT检查,并进行随访。从中挑选出经随访或病理证实的75例作为统计对象。结果75例患者共累及114个髋关节,X线诊断42个股骨头;CT为100个股骨头;ECT为102个股骨头;MRI为114个股骨头;6例坏死股骨头,病理为纤维肉芽组织增生和成骨,结果与FHN影像相符。结论各种影像方法对股骨头缺血坏死均有一定的诊断价值,但MRI诊断价值最高。

Objective To study the signs of X-ray, CT, ECT, MRI and the pathologic processes of the femoral head necrosis （FHN）. Meth- ods The examinations were done in 120 patients who were suspected with suffering from FHN. From them,75 cases with completely FHN were choosen as the candidates for this statistical analysis. Results 42 FHN were seen on X-ray and 100 were seen on CT, 102 were seen on ECT and 114 were seen on MRI. It had statistical significance to detect intraosteal focus in the femoral head by X-ray,CT,MRI and ECT. Conclusion The signs of X-ray,CT,ECT and MRI in FHN are consistent with their pathological processes. In contrast, MRI is the best way to examine and detect FHN.
