Purpose The aim of this study was to compare the esophageal findings of 2-deoxy-2-[ F-FDG uptake were visually analyzed. The maximum standardized uptake value (SUV max ) of the esophagus and around the esophagogastric (EG) junction was measured. EGD results were provided by the gastroenterologist. We compared the esophageal findings obtained using F-FDG uptake in the esophagus. Reflux esophagitis was diagnosed in 59 subjects, and 27 of these were classified as higher than Los Angeles classification A. With an increasing degree of reflux esophagitis observed on EGD, the SUV max in the esophagus and around the EG junction was also increased. Conclusion Our study showed that FDG uptake at the esophagus or the EG junction might be clinically significantly related to esophagitis. However, EGD performed before
