- Psoriatic arthritis frequently occurs in hand and wrist joints, mostly as monoarthritis or oligoarthritis, presenting a large spectrum of clinical and imaging findings. - MRI allows the visualization of bone marrow, soft tissue, articular and entheseal lesions, identifying subclinical arthritis and providing useful information regarding active inflammation. - New techniques such Dynamic Contrast-Enhanced MRI Conventional and Dual-energy CT can be used in the differentiation of others peripheral arthropathies.

MR and CT imaging findings of psoriatic arthritis of peripheral articulations will be illustrate and discussed: • Synovitis • Enthesitis • Tendinitis • Dactylitis and soft tissue oedema • Bone erosions and bone oedema • Destructive and proliferative bony changes, subluxation, and ankylosis MR and CT imaging findings of other types of peripheral inflammatory arthritis that can simulate psoriatic arthritis will also be illustrated. Potencial applications Dynamic Contrast-Enhanced MRI Conventional and Dual-energy CT for differential diagnosis of psoriatic arthritis and other inflammatory arthritis will be discussed.
