Abstract

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) ultrasound (US) steering committee provided an update at GRAPPA's 2022 annual meeting on activities to enable earlier diagnosis of psoriatic arthritis. An update of the Diagnostic Ultrasound Enthesitis Tool (DUET) study included preliminary reliability results for US enthesitis elementary lesions. Common scanning pitfalls were reviewed. New projects included widening the scope of US beyond large entheses and validating small point-of-care US probes to evaluate enthesitis.
