Abstract：Objective To study the diagnostic and staging value of MSCT in sacroiliac joint ( SIJ) disease of ankylosing spondyli-tis ( AS) . Methods 198 patients with clinically confirmed AS sacroiliitis were chosen to be examined by DR and CT, then six signs of the bilateral SIJ were evaluated to compare the differences between DR and CT in diagnosis and staging. Results The frequency of 6 signs in DR and MSCT were blurred articular surface (180, 201), articular facet sclerosis (181, 200), articular surface destruc-tion (176, 205), joint space stenosis (183, 183), joint space widening (186, 190) and ankylosis (186, 190);the diagnostic co-incidence rate was gradeⅠ44. 7%, Ⅱ55. 7%, Ⅲ58. 8%, Ⅳ62. 5% separately) . Conclusion MSCT can be used to detect more subtle changes than DR in AS SIJ, and it is better in classification diagnosis, especially in gradeⅠand Ⅱ.
