MR imaging can detect inflammatory changes in peripheral and axial joints and entheses in PsA before the classic destructive and proliferative changes are detected on radiographs, improving the possibilities for early diagnosis and objective monitoring of the disease process. Identification of certain MR features can help to suggest a specific diagnosis of PsA in peripheral forms of the disease.  Patterns of inflammation on MR imaging suggest that the different entheses are the primary target of inflammation in most of clinical forms of PsA.

Our purpose is to describe the spectrum of MR imaging findings in axial and peripheral joints and entheses in patients with Psoriatic Arthritis (PsA), emphasizing the ability of this technique to detect the inflammatory changes. Table of contents: - Clinical key points of PsA. - Technical MR imaging considerations. - MR features: Inflammatory changes: Enthesitis: major entheses, joint entheses Bone edema: subchondral, periarticular, diaphyseal Synovitis/tenosynovitis Widespread, extracapsular soft-tissue edema.         2. Destructive/proliferative changes. - MR imaging in the differential diagnosis of PsA. - Current role of MR imaging in PsA.
