摘　　要：目的:研究强直性脊柱炎的骶髂关节病变的影像表现。探讨影像学对强直性脊柱炎的骶髂关节病变影像学诊断价值。方法:对临床确诊的69例强直性脊柱炎的双侧SIJ摄X线平片,同时作CT扫描。总结其影像表现及病变分级,作平行对照研究,并进行统计分析。结果:强直性脊柱炎的骶髂关节病变的患者主诉以髋部疼痛、腰痛、弯腰受限、颈椎受限出现的百分率依次为:49.27%、36.23%、13.03%、1.44%。X-ray骶髂关节影像表现正常、关节变毛糙、模糊、硬化、关节融合的检出率分别为:13.04%、57.97%、27.53%、1.44%;CT分别为:0%、53.62%、44.92%、1.44%。X-ray与CT诊断的符合率从0级～Ⅳ级分别为:0%、15.38%、60.0%、76.92%、100%。结论:强直性脊柱炎的骶髂关节病变X线平片的早期不敏感,对临床怀疑而平片难以确诊的早期病变,CT检查有较高价值。平片表现为早期病变(0～Ⅱ级)的患者CT对其分级更为准确,可提高1～2个级别。Objective： To study imaging expression of sacroiliac joints disease in ankglosing spondylitis, To explore the value of imging expression and its diagnosis. Methods： X-ray and CT were used to the diagnosed 69 cases. The imaging features, and the stage of disease in each case were summerized. Parallel comparison research and statistical analysis were done. Results： The complains ankglosing spondylitis of sacroiliac joints disease were hip jiont pain, low back pain, limition of lumbar movement , limition of cervical vertebra , and its percentage are： 49.27%, 36.23%, 13.03%, 1.44% respectively. On the X-ray its imaging features were normal, joint become coarse, hardening and joint fusion, and its percentage were： 13.04%, 57. 97%, 27. 53%, 1. 44%, and CT expression percentage were： 0%, 53. 62%, 44. 92%, 1.44% respectively. Coincidence rate of X-ray and CT from 0-Ⅳ stage were： 0%, 15.38%, 60.0%, 76.92%, 100% respectively. Conclusion： At early stage X-ray is not sensitive on ankglosing spondylitis of sacroiliac joints disease, CT is more valuable at not sure cases in clinical. If X-ray shows at 0- Ⅱ stage its CT is more accurate.
