CT、MRI在成人股骨头缺血性坏死早期诊断中的应用价值

Application Value of CT and MRI on Early Diagnosis of Adult Femoral Head Necrosis

目的:探讨CT、MRI对成人股骨头缺血性坏死(ANFH)早期诊断的临床应用价值。方法:对29例42个早期ANFH的患者进行双髋关节X线平片、CT及MRI检查。结果:29例患者42个部位早期ANFH中,X线平片、CT及MRI的阳性准确率分别为42.9%、83.3%、97.6%。结论:CT是诊断早期ANFH的重要检查方法,明显优于X线平片检查,为成人ANFH的早期诊断带来帮助;MRI诊断早期ANFH比CT更具敏感性,并能准确分期,CT与MRI相结合,是诊断成人早期ANFH的可靠手段,为临床的早期治疗提供可靠依据。

Objective：To research the application value of CT and MRI detection in early diagnosis of avascular necrosis of the femoral head（ANFH）.Method：29 cases with ANFH were detecting 42 hips by the three kinds of scan with normal X-ray,CT and MRI.Result：The positive rate of the three methods in detecting diseases was 42.9% for the normal X-ray,83.3% for the CT and 97.6% for the MRI.Conclusion：Among the three image methods,MRI is the most sensitive one to diagnose the avascular necrosis of femoral head（ANFH）,the second is CT,the last is normal X-ray.
