Psoriatic arthritis (PsA) is an inflammatory joint disease characterised by arthritis and often enthesitis in patients with psoriasis, but presenting a wide range of disease manifestations in various patterns. Imaging procedures used in PsA are primarily conventional radiography, ultrasonography (US) and magnetic resonance imaging (MRI), whereas other modalities such as computed tomography are not routinely used. Imaging is an integral part of management of psoriatic arthritis for multiple reasons including establishing or confirming the diagnosis, determining extent of disease, monitoring change in disease e.g. activity and damage, assessing therapeutic efficacy, prognostication and identifying complications of disease or treatment, in the setting of clinical practise or clinical studies. These entirely different contexts may favour different imaging approaches. This talk will focus on the available data of different imaging modalities, particularly MRI and US, for predicting 1) the development of psoriatic arthritis in patients with psoriasis, 2) the response to therapy in patients with PsA and 3) the disease course in patients with PsA.
