CT和磁共振成像诊断股骨头坏死的临床对比研究

Clinical comparative study of CT and MRI in the diagnosis of necrosis of the femoral head

目的探讨CT和磁共振成像诊断股骨头坏死的临床价值。方法选择2016年6月至2017年6月本院收治的60例经手术病理检查确诊为股骨头坏死患者为研究对象,依照入院单双次序分为对照组和观察组,每组30例。对照组采用CT检查,观察组采用磁共振仪检查,分析两种检查方法的诊断结果。结果在股骨头坏死阳性确诊率上,观察组显著高于对照组(97%,80%),其差异具有统计学意义(P<0.05);在1期检出率上,观察组明显好于对照组,其差异具有统计学意义(P<0.05),在2、3、4期检出率上,两组无明显差异(P>0.05)。结论股骨头坏死患者应用磁共振成像检查能够在任意断面成像,明确患者具体病变部位,为其诊疗提供详实可靠的临床参考,具有重要的临床价值。

Objective To explore the clinical value of CT and MRI in the diagnosis of necrosis of the femoral head. Methods Methods from June 2016 to June 2017, 60 cases of osteonecrosis of the femoral head diagnosed by surgical pathology were selected and divided into control group and observation group, 30 cases in each group. The control group was examined by CT, and the observation group was examined by nuclear magnetic resonance （MR/）, and the results of the two methods were analyzed. Results The positive diagnosis rate of avascular necrosis of the femoral head, the observation group was significantly higher than the control group （97%, 80%）, the difference was statistically significant （P〈0.05）; in the 1 period and the detection rate of the observation group was significantly better than the control group, the difference was statistically significant （P〈0.05）, in 2, 3, 4 the detection rate, no significant difference between the two groups （P〉0.05）. Conclusion MRI can be used in imaging of any section of femoral head necrosis. It can provide specific and reliable clinical reference for diagnosis and treatment, and has important clinical value.
