摘　　要：目的:通过对比CT与MRI技术提高对强直性脊柱炎髋关节改变的诊断和分析水平。方法:本院选取2009年5月至2011年9月临床诊断为AS髋关节改变的患者66例,对其髋关节部位进行CT与MRI技术检查,将检查结果进行影像分析,分析结果评价CT与MRI技术检测AS髋关节改变的优劣势。结果:CT与MRI对AS髋关节改变显示概率分别为22.7%(15/66)和72.7%(48/66),两组间具有明显差异,P<0.05,具有统计学意义。66例强直性脊柱炎患者共132个髋骨关节侧位,CT显示异常的髋关节侧位为15个,MRI显示异常的髋关节侧位为90个,髋关节异常检查率分别为11.4%和68.2%,两组间具有显著性差异(P<0.05)。结论:MRI显示时AS髋关节受累的急性炎症改变优于CT,常显示为少量关节腔积液和滑膜异常强化。Objective：To improve the level of diagnosis and analysis of ankylosing spondylitis through the comparative study of CT and MRI techniques .Method：The CT and MRI of hip were performed in 66 pa-tients with ankylosing spondylitis in our hospital from May 2009 to September 2011 .The imaging data of 66 patients were analyzed to obtain the better detection technology for AS .Result：Abnormal changed were de-tected in 22.7%（15/66）by CT, and 72.7%（48/66） by MRI,and there was significant difference between the two groups.Among 132 hips in all 66 patients,abnormal changes were detected in 15 hips by CT,90 hips by MRI,and the hip abnormaly inspection rate were 11.4%and 68.2%respectively, with significant differ-ence between them（P〈0.05）.Conclusion：MRI can detect early acute inflammatory changes of hip joint that can not be showed by CT .Effusion of joint and synovial enhancement caused by synovitis are the most com-mon MRI findings of the hip in patients with AS .
