OBJECTIVES: The aim of the study was to evaluate the capability of fluorine-18-fluorodeoxyglucose (F-FDG)-positron emission tomography (PET)/computed tomography (CT) in the screening of musculoskeletal inflammation and injury of the shoulder region. MATERIALS AND METHODS: The study included 122 participants (69 men and 53 women) who complained of shoulder pain at rest and 122 age-matched and sex-matched controls who did not experience pain at rest. Standardized uptake values (SUVs) were calculated for both the left and right shoulders and compared using a four-point visual analog scale of subjective shoulder pain. Correlations between SUVs and uric acid and C-reactive proteins were also evaluated. RESULTS: SUVs for shoulder joints with rest and/or motion pain were significantly higher than those for pain-free shoulder joints. SUVs associated with mild and severe pain at rest were significantly higher than those associated with absence of pain at rest, and SUVs associated with moderate and severe pain on motion were significantly higher than those associated with absence of motion pain. Furthermore, SUVs were significantly correlated with uric acid in men (β=0.21, P=0.02) and in all participants (β=0.22, P<0.001). CONCLUSION: F-FDG-PET/CT may be useful for the screening of musculoskeletal inflammation and injury of the shoulder region. As shoulder pain is common, especially among elderly individuals, we should carefully consider the necessity of further examination when identifying the uptake of F-FDG in shoulder joints.
