目的：分析CT和MRI两种方法在股骨头缺血性坏死中的诊断价值。方法2011年1月~2013年5月我院收治的94例122髋股骨头缺血性坏死患者，均进行CT和MRI检测，以ARC0法为标准分期，比较两种方法的诊断准确率及影像学表现。结果 MRI诊断敏感率为98.4%（120/122），CT诊断敏感率为93.4%（114/122），MRI与CT诊断敏感率比较（x2=3.753，P＞0.05）。CT与MRI检出率，I期CT检出率显著低于MRI，两种检验方法比较（x2=3.844，P＜0.05），在Ⅱ期与Ⅲ期检出率上比较（x2=0.328、0.148，P＞0.05）。结论股骨头缺血性坏死中，MRI较CT均具有较高的诊断率，两者联合应用可以提高临床诊断率。但是在早期诊断中，MRI较CT更准确，因此对于股骨头缺血性坏死早期诊断中应该选用MRI作为检测诊断方法。

Objective To analyze the diagnostic value of CT and MRI two methods in diagnosis of ischemic necrosis of femoral head.Methods94 cases 122 hips of patients with ischemic necrosis of femoral head in our hospital from 2011 January to 2013 May were detected by CT and MRI, ARc0 method as the standard. Two diagnosis accuracy rate and imaging findings were compared.Results The sensitive rate in diagnosis of MRI and CT were 98.4% (120/122) and 93.4% (114/122), there was statistically significant (x2=3.753,P>0.05). The detection rate of I CT detection rate was significantly lower than that of MRI, two kinds of test methods were statistically significant (x2=3.844, P<0.05), The detection rates in phase II and III were statistically significant (x2=0.328, 0.148;P>0.05). Conclusion The diagnosis of MRI with CT has higher rate in the diagnosis of avascular necrosis of the femoral head, their combined application can improve the clinical diagnostic rate. But in the early diagnosis of CT, MRI is more accurate, so the early diagnosis of ischemic necrosis of femoral head should choose MRI as the detection and diagnosis method.
