Abstract：Rheumatic diseases(RD)are a group of systemic disorders affecting multiple systems,with chronic inflammatory responses in vascular and connective tissues as their main pathological basis.Due to its sensitive detection of metabolic activity and systemic inflammatory burden,18F-FDG PET/CT,has become increasingly important for early diagnosis,assessment of disease activity,and monitoring of treatment in RD.This article reviews the research progress of 18F-FDG PET/CT in various RD,including rheumatoid arthritis,polymyalgia rheumatica,idiopathic inflammatory myopathies,adult-onset Still's disease,systemic lupus erythematosus,IgG4-related disease,relapsing polychondritis,Sjögren's syndrome,spondyloarthritis,and Takayasu arteritis,etc.
