股骨头坏死患者CT与核磁共振的临床诊断价值

The Clinical Diagnosis Value on Patients With Avascular Necrosis of Femoral Head by CT and MRI

目的：探讨股骨头坏死患者CT与核磁共振的临床判断价值。方法选用我院于2013年6月-2014年2月间收治的股骨头坏死患者60例（118髋），将其随机分为观察A组和观察B组各30例（分别为58髋、60髋）。其中A组患者给予核磁共振（MRI）髋关节影像学检查，B组患者给予CT髋关节影像学检查。对比分析两组股骨头坏死的影像学表现与股骨头坏死检出率。结果118例可疑股骨头中，A组经MRI检查发现的股骨头坏死患者27例，检出率为90.00%，B组经CT检查发现的股骨头坏死患者18例，检出率为60.00%，二者差异具有统计学意义（P〈0.05）。结论在股骨头坏死患者的临床诊断中，采用核磁共振检查与CT检查相比较的方法，发现MRI检测股骨头坏死检出率高，诊断早期ANFH效果较好。

Objective To investigate the clinical value on patients with avascular necrosis of femoral head by CT and MRI. Methods 60 patients treated in our hospital with avascular necrosis of femoral head were selected from June 2013 to February 2014,who were divided into group A and group B randomly,30 cases in each group. A group with magnetic resonance imaging（MRI）examination,B group with CT. Results 118 cases of suspected femoral head,27 cases of avascular necrosis of femoral head were found in group A,the detection rate was 90%,18 cases of avascular necrosis of femoral head were found in group B,the detection rate was 60%. There was significant difference（P〈0.05）. Conclusion In the clinical diagnosis of patients with avascular necrosis of femoral head,after comparing between MRI and CT examination,MRI has high detection rate,and better diagnosis of early ANFH.
