Differentiation of axial spondyloarthritis-related lesions from degenerative lesions on Na[18F]Fluoride PET/CT in a longitudinal dataset of patients with radiographic axial spondyloarthritis.
PURPOSE To investigate longitudinal changes of Na[18F]Fluoride uptake in the axial skeleton of patients with radiographic axial spondyloarthritis (r-axSpA) during biological treatment, focusing on r-axSpA and degenerative (D) lesions. METHODS 20 active r-axSpA patients were included. Na[18F]Fluoride Positron Emission...
