Magnetic resonance imaging MRI allows visualization of soft tissue articular and entheseal lesions and provides a unique picture of the disease process that cannot be gained using other imaging modalities. This review focuses on the literature on MRI in psoriatic arthritis published from 1996 to July 2005. The MRI features discussed include synovitis tendonitis dactylitis bone oedema bone erosions soft tissue oedema spondylitis sacroiliitis and subclinical arthropathy. Comparisons have been drawn with the more extensive literature describing the MRI features of rheumatoid arthritis and ankylosing spondylitis. Introduction Magnetic resonance imaging MRI has advanced our understanding of many types of arthritis both with respect to inflammatory processes and articular damage. Psoriatic arthritis PsA has received less research scrutiny than rheumatoid arthritis RA in many areas including imaging 1 but this is likely to change because MRI outcome measures are increasingly being used in clinical trials of new therapeutic agents such as biologics 2 .
