Abstract
The introduction of MRI in spondyloarthritis (SpA) constitutes a major advance and is increasingly being implemented in clinical practice in cases in which clinical suspicion of SpA is high yet pelvic radiography is equivocal. Recent studies and development of consensus by international experts support the routine use of specific MRI sequences and scanning protocols for the evaluation of the sacroiliac joints in diagnostic work-up. There is also agreement that the finding of bone marrow edema in the sacroiliac joints carries a high probability of SpA, and emerging data indicate that the finding of erosion may also be diagnostically helpful, even in preradiographic SpA. Recent studies suggest that the diagnostic role of MRI may be further enhanced through the study of additional MRI sequences and prospective studies using systematic methodologies aimed at further scrutiny of structural lesions and the contribution of spinal imaging. Interest in MRI for SpA is poised for substantial growth.

MRI assessment of spinal inflammation in ankylosing spondylitis: standard clinical protocols may omit inflammatory lesions in thoracic vertebrae. Arthritis Rheum 2009; 61: 1187–1193. This report has major clinical practice implications in that it highlights the importance of using appropriate MRI scanning protocols that ensure adequate visualization of the lateral segments of the spine, where inflammatory lesions are frequently observed and are highly specific for SpA.
