Significance of 18F-Fluorodeoxyglucose Uptake at the Gastroesophageal Junction: Comparison of PET to Esophagogastroduodenoscopy

Background Positron emission tomography-computed tomography (PET/CT) occasionally reveals unexpected uptake of 18F-fluorodeoxyglucose (18F-FDG) at the gastroesophageal junction (GEJ). The aim of this study was to determine the importance of unexpected 18F-FDG uptake at the GEJ on PET/CT by correlating this finding with endoscopy results.
