GRAPPA Debate: Is Plain Radiography in Psoriatic Disease Still Necessary?

Plain radiographs have been widely used in psoriatic disease (PsD) for diagnosis, classification, and monitoring of structural damage. However, with the emergence of other imaging modalities such as ultrasound, magnetic resonance imaging, and computed tomography, the necessity of plain radiographs in PsD is debatable. At the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2025 annual meeting in Bogotá, Colombia, Drs. William Tillett and Arthur Kavanaugh were invited to debate the topic "Plain radiography in psoriatic disease: is it still necessary?" Each presented evidence-based arguments, incorporating multiple data sources, including clinical trials, to support their positions for and against the topic, respectively. This article summarizes their debate for the broader PsD community.
