股骨头缺血性坏死的影像学检查及比较

The Image Diagnose and Comparison of Avascular Necrosis of Femoral Head

对 5 1例缺血性坏死股骨头 (ANFH)进行 X线、SPECT、MRI图像检查 ,根据早、中、晚期图像评价标准对其分别进行分期。结果 SPECT、MRI对 ANFH早 -中期诊断的灵敏度分别为 5 0 .9%、6 0 .8% ,X线的灵敏度为 39.0 % ;对晚期诊断的灵敏度差别不明显。这表明 SPECT、MRI对 ANFH早、中期诊断较 X线敏感。因此在判断早期病变时 ,采用 X线诊断的同时 ,应做 SPECT或

cases with avascular necrosis of femoral head(ANFH) are diagnosed and staged with X ray,SPECT,MRI based on image evaluation standard. The sensitivity of X ray,SPECT,MRI in early mediate stage ANFH are 39.0%,50.9%, 60.8% respectively.The results indicate that SPECT and MRI are more sensitive than X ray in diagnosing early stage ANFH.
