Abstract：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.
