AI Article Synopsis
- The OMERACT MRI Task Force has made progress on the psoriatic arthritis MRI score (PsAMRIS), presenting a longitudinal evaluation involving multiple readers at OMERACT 10 using MRI data from extremities.
- They aim to refine this score further by acquiring more imaging datasets specifically for psoriatic arthritis (PsA).
- The Task Force is also exploring a semiquantitative method for assessing joint space narrowing as an addendum to the rheumatoid arthritis MRI scoring system (RAMRIS), while investigating the presence of subclinical synovitis and focusing on longitudinal studies of low disease activity datasets.
Article Abstract
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.
