【摘要】 目的探讨股骨头缺血性坏死(ANFH)的影像学表现及各种影像检查方法对其诊断价值。方法回顾性分析了28例40髋ANFH病例,男23例,女5例,平均年龄36岁,病程3个月～8a。所有病例均行普通X线平片、CT及MRI检查。结果 X线平片、CT及MRI发现ANFH的阳性率分别是75.6%、84.5%及97.8%。结论 MRI诊断ANFH最敏感,其次为CT,最后为普通X线平片检查。更多还原

【Abstract】 Objective To study the imaging performance of the conventional X-rayfilms,CTand MRI in avascular necrosis offemoral head (ANFH) and their diagnostic value on ANFH. Methods To tally 28 cases with 40 femoral ANFH were reviewed,of whom 5 cases were male,average age was 36 years old and the clinical history was from 3 month to 8 years.All cases were performed by the three kinds of scan modes which included conventional X- ray films,CT and MRI. Results The sensitivity of the three methods in detecting the disease was 75.6% for the conventional X- ray films,84.5% for the CT and 97.8% for the MRI. Conclusion Among the three image methods,MRI is the most sensitive one to diagnose the ANFH,the second is CT,the last is convential X- ray films.更多还原
