The purpose of this study is to determine the utility of high resolution 7 Tesla scanning for patients with ankylosing spondylitis in different stages of pathology progression. Fifteen patients were imaged on a whole body 7T system. Using a custom-built RF coil high spatial resolution 3-point Dixon images of the SI joints were acquired rendering water- and fat-only images with excellent delineation of the whole SI joint. 7 Tesla MRI is a promising adjunct imaging modality for early detection and following the progression of ankylosing spondylitis.
