The aim of this study was to evaluate the performance of a 3D-UTE sequence in the detection of sacroiliac joint cartilage and bone cortex abnormalities in patients with clinically confirmed ankylosing spondylitis. T2* derived from 3D-UTE displayed potential as a quantitative measure to diagnose ankylosing spondylitis.
