ABSTRACT
Objective To explore the influencing factors ofF-Fluorodeoxyglucose(F-FDG) uptake of brown adipose tissue(BAT) in PET/CT imaging by performing meta-analysis.Methods Relevant articles published between 1980 and 2016 were searched in PubMed,EMBASE,Web of Science,CBM,WanFang Data,CNKI,and VIP.The factors of gender,season and age were extracted according to the inclusive criteria.Meta-analysis was performed to analyze the factors.Results The merger OR value and 95% CI ofF-FDG uptake of BAT with gender,age,season were 2.67 (2.30-3.11),2.17 (1.38-3.39),and 15.35 (4.72-49.95) respectively.TheF-FDG uptake rate of BAT was 2.16 times in females as that in males,8.67 times in the minors as that in the adults,and 1.94 times in winter as that in summer.Conclusion Gender,season,and age are risk factors forF-FDG uptake of BAT.
