CT、MRI在早期股骨头缺血坏死诊断中的价值

The value of CT and MRI in early diagnosis of avascular necrosis of femoral head

目的:探讨CT、MRI检查在成人早期股骨头缺血坏死诊断中的价值。方法:对90例成人股骨头坏死患者分别采用CT和MRI检查,对比两种检查方法的诊断敏感度和早期定性敏感度。结果:MRI早期检查定性敏感度明显高于CT(P<0.05)。结论:CT和MRI均可作为成人股骨头坏死的常规影像诊断依据,但在早期股骨头坏死的诊断中,MRI早期检查定性敏感度较高。

Objective:To investigate the value of CT and MRI in the diagnosis of avascular necrosis of femoral head in adults.Methods:90 adult patients with osteonecrosis of the femoral head were examined by CT and MRI respectively.The diagnostic sensitivity and early qualitative sensitivity of the two methods were compared.Results:The qualitative sensitivity of MRI was significantly higher than that of CT(P<0.05).Conclusion:CT and MRI can be used as the basis for routine imaging diagnosis of femoral head necrosis in adults,but in the early diagnosis of necrosis of the femoral head,the qualitative sensitivity of early MRI examination is higher.
