【摘 要】目的：探讨X线、CT和MR检查早期股骨头缺血坏死的应用价值。方法：对62例早期股骨头缺血坏死患者进行x线、CT、MR三种影像学方法进行对比分析。结果：经不同的诊断方式检查后发现，针对早期股骨头缺血坏死患者实施MR检查的诊断符合率（93.55%）明显高于CT诊断符合率（66.13%）及X线诊断符合率（25.81%），且CT与X线检查后的诊断符合率亦存在差异（P<0.05），

且差异具有统计学意义。结论：三种影像诊断方法对早期股骨头缺血坏死诊断的符合率存在较大的差异，一般推荐以MR检查进行诊断，MR诊断的敏感性高，且不存在电离辐射的缺陷，利于患者疾病的确诊及治疗方案的确定。

【Abstract】Objective： To investigate the value of X-ray， CT and MR in detecting early avascular necrosis of the femoral head. Methods： Sixty-two patients with early avascular necrosis of the femoral head underwent X-ray， CT and MR imaging methods. Results： After examination by different diagnostic methods， the diagnostic coincidence rate （93.55%） for MR examination in patients with early avascular necrosis of the femoral head was significantly higher than that of CT diagnosis （66.13%） and the compliance rate of X-ray diagnosis （25.81%）. There was also a difference in the diagnostic coincidence rate between CT and X-ray examination （P<0.05）.And the difference is statistically significant. Conclusion： There are great differences in the coincidence rate between the three imaging diagnosis methods for the diagnosis of early avascular necrosis of the femoral head. It is generally recommended to use MR examination for diagnosis. The sensitivity of MR diagnosis is high， and there is no defect of ionizing radiation， which is conducive to the diagnosis of the disease. And the determination of the treatment plan.

股骨头缺血性坏死主要是由于股骨头学工出现突然中断或受到损伤，引发骨细胞或骨髓成分出现死亡后修复，最终导致股骨头结构出现变化（股骨头塌陷、关节功能障碍等）的疾病，属于临床中治疗难度较大的骨科疾病之一。且股骨头缺血性坏死是由创伤性（股骨颈骨折、髋关节脱位等）及非创伤性（皮质类固醇的应用或大量饮酒等）两大因素导致的[1]，患者临床症状主要表现为肌肉萎缩、患肢缩短、外展及内旋受限、局部压痛等，严重影响患者身体健康及正常生活。针对股骨头缺血性坏死患者实施早期诊断能为患者赢得最佳治疗时间，为了分析三种检查方式对于诊断股骨头缺血性坏死的价值，我院针对收治的62例股骨头缺血性坏死患者进行了观察及检查对比分析。……
