Psoriatic arthritis (PsA) presents with diverse features of musculoskeletal inflammation that affect both axial and peripheral joints as well as entheses, tenosynovium, and bursae. Magnetic resonance imaging (MRI) is the imaging modality that is uniquely capable of identifying pathology in all these structures. The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) Magnetic Resonance Imaging Working Group has increasingly explored diverse MRI methodologies for the purposes of quantifying inflammatory and structural abnormalities in clinical trials and research. The 2020 GRAPPA virtual workshop presented an opportunity to review progress in the field, summarize the status of MRI scoring systems developed for PsA, and review representative patient cases.
银屑病关节炎（PsA）表现为肌肉骨骼炎症的多种特征，累及中轴和外周关节以及附着点、腱鞘和滑囊。磁共振成像（MRI）是唯一能够识别所有这些结构病变的成像方式。银屑病和银屑病关节炎研究与评估小组（GRAPPA）磁共振成像工作组越来越多地探索各种MRI方法，以在临床试验和研究中量化炎症和结构异常。2020年GRAPPA虚拟研讨会提供了一个机会，来回顾该领域的进展、总结为PsA开发的MRI评分系统的现状，并回顾具有代表性的患者病例。
