Ultrasound (US) is a valuable imaging modality that can accurately identify relevant features of psoriatic arthritis (PsA), such as synovitis, tenosynovitis, and enthesitis. The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) Ultrasound Committee ran a workshop during the annual GRAPPA meeting that was held in July 2020. The group presented the following 3 topics: (1) the transition from psoriasis to PsA and the role of US; (2) the effect of biomechanical forces on the entheses in health and disease, and insight for PsA pathogenesis; and (3) differentiation of enthesitis from pain sensitization: use and limitations of clinical and sonographic evaluation of enthesitis. This article summarizes the key messages from this workshop.
超声（US）是一种有价值的成像方式，可准确识别银屑病关节炎（PsA）的相关特征，如滑膜炎、腱鞘炎和附着点炎。银屑病关节炎研究和评估协会（GRAPPA）超声委员会在 2020 年 7 月举行的 GRAPPA 年会上举办了一个研讨会。该小组介绍了以下 3 个主题：（1）从银屑病到 PsA 的转变和 US 的作用；（2）生物力学对健康和疾病中附着点的影响，以及对 PsA 发病机制的认识；（3）附着点炎与疼痛敏化的鉴别：附着点炎的临床和超声评估的应用和局限性。本文总结了该研讨会的关键信息。
