^(99m)Tc-MDP骨因子分析显像、骨三相显像及骨断层显像对股骨头缺血性坏死诊断的比较

Comparative study of ^(99m)Tc-MDP bone factor analysis imaging,3-phase bone imaging and bone SPECT in diagnosis of FHIN

目的 寻找对早期股骨头缺血性坏死更有效的诊断方法。方法 选择 10例 (2 0个髋 )正常人和 2 8例 (35个髋 )股骨头缺血性坏死 (FHIN)患者分别进行骨因子分析显像、骨三相显像和骨断层显像 ,得到 3组结果并将 3组结果进行对比分析。结果 对Ⅰ、Ⅱ期FHIN患者诊断的灵敏度以99mTc MDP骨因子分析显像最高 ,为 76 4% ,骨断层显像为5 2 9% ,骨三相显像 35 2 9%。骨因子分析与骨三相相比有显著性差异 (P <0 0 5 ) ,而 3者对Ⅲ期以上FHIN诊断的灵敏度基本一致。结论 99mTc

Objective:To search and more effective way to diagnose early femoral head ischemic necrosis(FHIN). Methods 99m Tc MDP bone factor analysis imaging, 3 phase bone imaging and bone SPECT were respectively performed on 20 healthy persons and 35 patients with FHIN. The results of there groups were gained. These results were analysed contrastively. Results For bone factor analysis imaging, the sensitivity of diagnose of FHIN in Ⅰ,Ⅱstage was 76^4% bone 99m Tc MDP SPECT,52 9%;3 phase bone imaging, 35 29%. But the sensitivity of diagnosis of FHIN exceeding Ⅲ stage of illness, 99m Tc MDP bone factor analysis imaging is more valuable 3 phase bone imaging and bone 99m Tc MDP SPECT.
