Identifying Axial Spondyloarthritis in Inflammatory Bowel Disease Patients Utilising Computed Tomography.

The diagnosis of axial spondyloarthritis (axSpA) is hampered by diagnostic delay. Computed Tomography (CT) undertaken for non-musculoskeletal (MSK) indications in patients with inflammatory bowel disease (IBD) offers an opportunity to identify sacroiliitis for prompt rheumatology referral. The study aims to identify what proportion of IBD patients who underwent abdominopelvic CT for non-MSK indications have axSpA and explore the role of a standardised screening tool to prospectively identify axSpA on imaging.
