Abstract：Objective:To study the diagnosis effect of X-ray and spiral CT for sacroiliac joint in ankylosing spondylitis.Method:45 cases with sacroiliac joint in ankylosing spondylitis from March 2011 to March 2014 in our hospital were studied.All the patients were examined with X-ray and spiral CT.After checking,the diagnostic hierarchical situation of the two methods were recorded and analyzed and sacroiliac joint detection rate of all types of signs were compared. Result:The diagnostic effect of spiral CT 0-Ⅱgrade sacroiliac joint(early lesions ) was better than X-ray,the deviation of X-ray and spiral CT for patients with stageⅢ-Ⅳdiagnosis was small.X-ray of the articular surface of the fuzzy detection rate(30.00%) was significantly higher than that of spiral CT(15.56%),there was significant difference (χ2=7.6610,P=0.0056),spiral CT of articular cartilage and bone erosion detection rate(66.67%) was significantly higher than that of X-ray(51.11%),two check were significantly different(χ2=4.4977,P=0.0339).Conclusion:Spiral CT in early ankylosing spondylitis sacroiliac joint is better than X-ray diagnosis,and the sensitivity of X-ray and spiral CT in advanced ankylosing spondylitis sacroiliac joint disease diagnosis are the same.
