目的探讨螺旋CT在强直性脊柱炎骶髂关节病变诊断中的应用价值。方法收集强直性脊柱炎骶髂关节病变的患者117例，均行X线平片和螺旋CT检查，对比分析两者的诊断效果。结果螺旋CT诊断骶髂关节对各级病变准确数高于X线平片，差异有统计学意义(P<0.05)。螺旋CT对关节面侵蚀、软骨钙化、关节面下囊变和骨质增生、软组织肿胀等的检出率高于X线平片，差异有统计学意义(P<0.05)。结论螺旋CT可以清晰显示强直性脊柱炎骶髂关节病变的组织特征，客观准确地反应骶髂关节受累程度，为临床诊断和治疗提供重要的影像学依据。

Objective To investigate the value of spiral CT in diagnosis of sacroiliac joint disease in ankylosing spondylitis. Methods 117 ankylosing spondylitis patients who all underwent spiral CT and X-ray examinations were chosen, comparative analysis of the effect of both diagnoses was made. Results Spiral CT in the diagnosis of sacroiliac joint lesions was more accurate at all levels than X-ray plain film, and the difference was statistically significant (P<0.05). Rate of detection by spiral CT in articular surface e-rosion, calcified cartilage, subchondral cystic degeneration, hyperplasia of bone and soft tissue swelling was higher than that of X-ray plain film, with statistically significant difference (P<0.05). Conclusion Spiral CT could clearly show the organizational features of sacroiliac joint in ankylosing spondylitis, objective and accurate response of sacroiliac joint involvement, and provide important imaging evidence for clinical diagnosis and treatment.
