Imaging in Psoriatic Arthritis

Abstract

Psoriatic arthritis (PsA) is an inflammatory joint disease characterized by arthritis and often enthesitis in patients with psoriasis, presenting a wide range of manifestations in various patterns. Imaging procedures are primarily conventional radiography, ultrasonography (US), and magnetic resonance imaging (MRI); other modalities such as computed tomography are not used routinely. Imaging is an integral part of management of PsA. In this article, we provide an overview of the status, virtues, and limitations of imaging modalities in PsA, focusing on radiography, US, and MRI.
