X线与MRI诊断早期股骨头坏死的临床价值

Clinical value of X-ray and MRI in the diagnosis of early femoral head necrosis

目的探讨X线与MRI诊断早期股骨头坏死的临床价值。方法回顾性分析本院2017年10月至2019年4月收治的48例髋部疾病患者的临床资料,患者均经手术证实。入院后,先行X线检查,再行MRI检查。比较两种检查方式对股骨头坏死的诊断结果。结果MRI诊断股骨头坏死的准确度、灵敏度明显高于X线(P<0.05)。MRI对Ⅰ、Ⅱ期股骨头坏死的检出率均高于X线(P<0.05)。结论相较于X线,MRI对股骨头坏死的诊断准确率更高,能帮助医师准确判断疾病分期情况。

Objective To investigate the clinical value of X-ray and MRI in the diagnosis of early femoral head necrosis.Methods The clinical data of 48 patients with hip disease admitted in our hospital from October 2017 to April 2019 were retrospectively analyzed,and all patients were confirmed by surgery.After admission,all patients were examined by X-ray,followed by MRI examination.The diagnosis results of two examination methods for femoral head necrosis were compared.Results The accuracy and sensitivity of MRI in the diagnosis of femoral head necrosis were significantly higher than those of X-ray(P<0.05).The detection rates of femoral head necrosis in stageⅠandⅡby MRI were higher than those by X-ray(P<0.05).Conclusion Compared with X-ray,MRI is more accurate in diagnosing femoral head necrosis,which can help doctors accurately judge the disease stage.
