摘　　要：目的对比分析X线、CT、MRI及SPECT对早期股骨头缺血坏死(avascular necrosis of femoral head,ANFH)的诊断价值。方法经影像学诊断、手术治疗或骨穿最后病理证实的180例ANFH患者,对其X线平片、CT、MRI及SPECT影像资料进行回顾性分析,总结归纳其影像特点。结果X线、CT、MRI及SPECT对诊断早期ANFH的阳性率及准确率分别是25%、75%、95%、100%和20%、65%、85%、85%,以上4种检查手段综合应用对病变检出的阳性率为100%,诊断准确率为98%。结论4种影像检查方法综合应用可以明显提高病变的检出率及诊断的准确性。Objective To compare the diagnostic value of X - ray, CT, MRI and SPECT in avascular necrosis of femoral head （ ANFH ）. Methods X -ray,CT,MRI and SPECT findings of ANFH proved by pathology in 180 cases were respectively analyzed and summarized. Results X - ray,CT,MRI and SPECT ,the diagnostic sensitivity was 25% ,75% ,95% and 100% respectively,the diagnostic accuracy was 20% ,65% ,85% and 85% respectively,and the diagnostic sensitivity and accuracy was 100% and 98% respectively all together of X - ray, CT,MRI and SPECT. Conclusion The diagnostic sensitivity and accuracy of ANFH will observably improve in case of combining X - ray, CT, MRI with SPECT.
