Emerging Imaging Techniques in Spondyloarthritis: Dual-Energy Computed Tomography and New MRI Sequences

Rheum Dis Clin North Am. 2020 May;46(2):287-296. doi: 10.1016/j.rdc.2020.01.010.


Imaging of the sacroiliac joint plays a critical role in the classification of patients with axial spondyloarthritis. New imaging techniques are emerging, changing the way clinicians look at the sacroiliac joint. This article introduces the novel techniques in imaging of spondyloarthritis, including dual-energy computed tomography and new MRI sequences, with a focus on the imaging of bone marrow edema and erosions of the sacroiliac joint.

Keywords: Dual-energy computed tomography; MRI; Sacroiliac joints; Spondyloarthritis.
