Compared to conventional clinical, biochemical and radiographical examinations, magnetic resonance imaging (MRI) offers improved sensitivity to early inflammatory and destructive changes in peripheral joints in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and other inflammatory joint diseases. Furthermore, MRI measures provide high sensitivity to change and prognostic value.
Accurate and reproducible assessment requires strict definitions and validated assessment methods. Such methods can be qualitative, semiquantitative or quantitative. The present talk will outline currently available definitions and assessment systems of inflammatory and destructive changes in RA and PsA. The most used methods, i.e the RAMRIS (RA MRI scoring system) and PsAMRIS (PsA MRI scoring system), both developed by the OMERACT group, will be described, as will recent alternative approaches including whole-body MRI, dynamic contrast-enhanced MRI and volume quantification.
At the end of the talk, quiz cases for audience participation will be presented.
