FAQ: What Role Does Power Doppler Ultrasound Play in Detecting Subclinical Inflammation/Enthesitis?

March 2026

Power Doppler ultrasound is transforming how clinicians detect subclinical enthesitis in conditions like psoriatic arthritis (PsA) and spondyloarthritis (SpA). In this educational segment, Audrey Gibson, PA-C explains how Power Doppler imaging can identify active inflammation at tendon and ligament insertion sites by visualizing increased blood flow—often before symptoms appear on physical exam.

This technology helps clinicians uncover hidden disease activity, risk-stratify patients with psoriasis who may develop psoriatic arthritis, and monitor response to biologic therapies. By detecting inflammation earlier, Power Doppler ultrasound supports more proactive treatment decisions and improved long-term outcomes for patients with inflammatory arthritis.
