MRI in seronegative spondyloarthritis: imaging features and differential diagnosis in the spine and sacroiliac joints

AJR Am J Roentgenol. 2013 Jan;200(1):149-57. doi: 10.2214/AJR.12.8858.


Objective: Radiologists should be familiar with MRI findings suggestive of spondyloarthritis and its differential diagnosis. Because most publications describing these features are found in the rheumatologic literature, the purpose of this review is to present these imaging findings of axial spondyloarthritis to radiologists.

Conclusion: New imaging outcomes have improved the diagnosis and follow-up of spondyloarthritis and the assessment of therapeutic modalities. Diagnostic criteria include MRI of the sacroiliac joint, which facilitates earlier diagnosis.
