Imaging features of psoriatic arthritis and Reiter's syndrome.

摘要

Psoriatic arthritis and Reiter's Syndrome are seronegative spondyloarthropathies with characteristic, yet nonspecific, radiographic findings. Radiographic diagnosis is based upon recognition of the classic morphologic changes and knowledge of the articular distribution. Other imaging modalities such as computed tomography (CT), radionuclide imaging, magnetic resonance (MR) imaging, and ultrasonography are also utilized and play specific roles in the evaluation of Psoriatic arthritis and Reiter's Syndrome.
