The OMERACT Magnetic Resonance Imaging (MRI) Task Force has developed and evolved the psoriatic arthritis MRI score (PsAMRIS) over the last few years, and at OMERACT 10, presented longitudinal evaluation by multiple readers, using PsA datasets obtained from extremity MRI magnets. Further evaluation of this score will require more PsA imaging datasets. As well, due to improved image resolution since the development of the original rheumatoid arthritis MRI scoring system (RAMRIS), the Task Force has worked on semiquantitative assessment of joint space narrowing, and developed a reliable method as a potential RAMRIS addendum, although responsiveness will need to be evaluated. One of the strengths of MRI is the ability to detect subclinical synovitis, so the group worked on obtaining low disease activity/clinical remission datasets from a number of international centers and presented cross-sectional findings. Subsequent longitudinal evaluation of this unique resource will be a major continuing focus for the group.
过去几年中，OMERACT 磁共振成像（MRI）工作组一直在开发和完善银屑病关节炎 MRI 评分（PsAMRIS），并在 OMERACT10 会议上，使用从四肢 MRI 磁体获得的 PsA 数据集，由多位读者进行了纵向评估。要进一步评估该评分，还需要更多的 PsA 成像数据集。此外，由于最初的类风湿关节炎 MRI 评分系统（RAMRIS）开发以来图像分辨率的提高，工作组一直在研究关节间隙狭窄的半定量评估，并开发了一种可靠的方法作为潜在的 RAMRIS 附录，尽管需要评估其反应性。MRI 的优势之一是能够检测亚临床滑膜炎，因此该小组从多个国际中心获得了低疾病活动/临床缓解数据集，并提出了横断面研究结果。随后对这一独特资源的纵向评估将是该小组的一个主要持续重点。
