Abstract:
The ability to visualize musculoskeletal structures with high-resolution ultrasound is an asset to understanding the complexity of psoriatic arthritis (PsA). During the 2021 Annual Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) meeting, 3 topics were presented and discussed in the ultrasound workshop: (1) the progress on the Diagnostic Ultrasound Enthesitis Tool (DUET) project; (2) the sonographic evaluation of joints in PsA-GRAPPA joint project; and (3) extrasynovial lesions in PsA. The ultrasound group aims to develop sonographic tools that are feasible and can be used in standard care to diagnose PsA early. The discussions around these topics will shape the group's work toward developing a composite index to diagnose PsA early.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
