Imaging of Inflammatory Arthritis in Adults: Status and Perspectives on the Use of Radiographs, Ultrasound, and MRI.

The term inflammatory arthritis encompasses a variety of conditions featuring synovial inflammation as a defining characteristic, with resultant local tissue damage occurring over time. These arthritides often share overlapping clinical and imaging characteristics, although the pattern of joint involvement, specific appearance of pathologic changes, and associated findings often allow imaging-based differentiation or individual arthritides.
