However, this assumption is incorrect.Ĭreating an MR image is a complicated process that depends on tissue characteristics of the patient including flow and motion, MR machine parameters and environmental factors. 4 Thus rheumatologists will see more and more MR images and tend to consider an MR image and MR protocols as stable as a conventional X-ray. ![]() 3 Although there are no evidence-based guidelines for the use of MRI in the diagnostic process of RA, there is increasing evidence that MRI is valuable in the prognostication of patients withClinically Suspect Arthralgia. ![]() The use of MRI-detected synovitis to assess the extent of joint inflammation is incorporated in the 2010 EuropeanLeague Against Rheumatism/AmericanCollege of Rheumatology classification criteria for RA. MR images are frequently used as outcome measure in clinical trials now that clinically relevant radiographic joint damage has become infrequent. MRI also has a role in scientific studies in RA. Although classification criteria are not developed as an aid in the diagnostic process and the value of MRI is demonstrated in light of classification criteria, its use has expanded to regular care. 1 2 Sacroiliitis is earlier detectable with MRI than with radiographs, and therefore, the performance of MRI contributes to earlier classification of patients. ![]() It is role is most prominent in SpA, where MRI-detected sacroiliitis is part of the Assessmentin Spondyloarthritis International Society classification criteria. MRI is increasingly used, for instance, in patients with (suspected) spondyloarthitis (SpA) or rheumatoid arthritis (RA).
