摘要：

目的 分析CT与MRI在早期股骨头坏死诊断中的应用价值。方法 回顾性分析我院2015年6月至2016年6月收治的62例早期股骨头坏死患者的临床资料，所有患者均经手术病理诊断确诊，均给予CT检查与MRI检查。对比两种检查方式的股骨头坏死检出率和早期股骨头坏死典型征象显示情况。结果 CT与MRI对Ⅲ期、Ⅳ期股骨头坏死的检出率比较，无显著差异（P>0.05）；MRI 对Ⅰ期、Ⅱ期股骨头坏死检出率高于CT，差异有统计学意义（P<0.05）；与CT比较，MRI检查方式的总检出率明显更高，差异有统计学意义（P<0.05）。MRI对骨小梁模糊、线样征及骨髓水肿显示率高于CT（P<0.05）；CT与MRI对局部囊变显示率比较，无显著差异（P>0.05）。结论 MRI检查应用于早期股骨头坏死诊断中的效果明显优于CT 检查方式，值得在临床工作中推广应用。

ABSTRACT: Objective To analyze the value of CT and MRI in the diagnosis of early femoral head necrosis. Methods The clinical data of 62 patients with early femoral head necrosis admitted in our hospital from June 2015 to June 2016 were analyzed retrospectively. All patients were confirmed with pathology, and given CT and MRI detection. The detection rate of femoral head necrosis and early signs of typical display status of two detection methods were compared. Results There was no significant difference between CT and MRI in detecting the necrosis of femoral head in stage Ⅲ and Ⅳ (P>0.05); the detection rates of MRI in stage Ⅰ and Ⅱ were higher than those of CT, the differences were statistically significant (P< 0.05); compared with CT, the total detection rate of MRI detection was significantly higher (P<0.05); MRI showed a higher rate of trabecular bone trauma, line sign and bone marrow edema than CT, the difference was statistically significant (P<0.05); CT and MRI showed no significant difference in local cystic manifestation (P >0.05). Conclusion The value of MRI examination is higher than CT examination in early diagnosis of femoral head necrosis. It is worthy to be applied in the clinical diagnosis.
