Objective To evaluate and analyze the clinical value of MRI and CT in the diagnosis of sacroiliac joint lesions of ankylosing spondylitis. Methods 78 cases with ankylosing spondylitis underwent MRI and CT scanning to judge the degree of lesions, and the results were compared to the clinical bone abnormality rate. Results The sensibility of MRI to examine sacroiliac lesions of ankylosing spondylitis I were 33.33% (26/78), which was significantly higher than CT 17.95% (14/78) (P<0.05). There was no statistical significance (P>0.05) to diagnose sacroiliac lesions of severer than ankylosing spondylitis II by MRI and CT. The detectable rate of bone abnormality of CT was significantly higher than MRI (P<0.05). Conclusion Compared with MRI, CT has a higher resolution, which can effectively diagnose sacroiliac joint lesions. Articular cartilage abnormalities and fat deposition can be showed clearly by MRI, and MRI is always used in the early diagnosis of sacroiliac joint lesions of ankylosing spondylitis and to provide basis for the the early diagnosis and treatment of sacroiliac joint lesions of ankylosing spondylitis.
