Psoriasis is a common chronic immune mediated skin disease. Psoriatic arthritis occurs in a variable, albeit considerable percentage of psoriatic patients which ranges from 10 to 30% depending on the studied population. Psoriatic arthritis may be present in different clinical forms whose major features are synovitis and/or enthesitis. In most patients, psoriasis precedes the clinical onset of the joint inflammatory disease. A number of studies have reported the presence of subclinical synovitis and enthesopathy detected by imaging techniques (e.g. MRI, ultrasound) in a higher percentage of psoriatic patients without musculoskeletal symptoms compared to controls. Some preliminary data on the predictive value of these imaging findings in relation to psoriatic arthritis development have been reported. This lecture offers an update of imaging modalities as biomarkers in psoriasis and psoriatic arthritis.
