Purpose:

To compare conventional radiography and Computed tomography for evaluation of radiolographic progression in ankylosing spondlitis

Methods:

All patient fulfilled the modified New York diagnostic criteria for AS and visited at Neo Medical Center of Kyung Hee university from March. 1, 2008 to February.1 2009. Assessment of radiolographic progression in conventional x-ray and computed tomography was performed with Stoke Ankylosing Spondylitis Spinal Score. All images were read twice and blindly by two readers.

Results:

total 339 patients with AS were examined. Disease duration is less than 10 years and the mean age is 30.5±5.7 years. The proportion of male to female is 3:1 and 90.1% was HLA-B27 positive. Total SASSS is 15.9± 11.6 in X-ray and 19.7 ± 8.3 in CT. In sclerosis, syndesmophyte and bridging CT detected more than X-ray, but did not in erosion and squaring, significantly. There were significant differences in SASSS of conventional radiography versus those of CT in all L-spine level. Especially bone bridge and syndesmophyte was significantly detected when 3 dimensional reconstruction.

Conclusion:

Conventional X-ray overestimates Erosion and squaring and underestimates sclerosis, syndesmophyte and bridging. Our study suggests that the CT is more appropriate method than X-ray for assessing radiographic change in AS.
