Ultrasound is a useful technique for visualizing bone abnormalities in small joints, assessing the extent of disease and identifying inflammatory changes, monitoring treatment, and guiding intra-articular steroid interventions. The European League Against Rheumatism notes that ultrasonography and power Doppler techniques enable the evaluation of synovitis by detecting thickening of the synovial membrane of inflamed joints and bursae or tendon sheaths.

Nail psoriasis is a refractory disease that affects up to 80% of patients with psoriatic arthritis. On ultrasound, a prominent bilayer is seen at the base of healthy nails. Obliteration of the bilayer is seen in psoriatic onycholysis.
