股骨头缺血性坏死的MRI诊断价值

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。

Applied value of MRI in diagnosing the avascular necrosis of femoral heads

Objective To study the imaging performance of the ennventional X-ray films, CT and MRI in avaseular necrosis of femoral 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 o12l and the clinical histoD＇ 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 deteefing 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 sen- sitive one to diagnose the ANFH, the second is CT, the last is eonvential X-ray films.
