Positron emission tomography/computed tomography (PET/CT) applies the uptake of 18-fluorodeoxyglucose in the diagnosis of cancer. Our aim was to compare DWIBS/T2 and PET/CT in patients with upper gastrointestinal cancers. Methods: Patient records, including imaging results from July 2012 to March 2015, were analyzed retrospectively. Four men (age, 72.5±5.3years) and ten women (age, 71.6±4.0years) were enrolled in this study. The numbers of patients with esophageal cancer, gastric cancer, gastrointestinal stromal tumor, and duodenal cancer were one, eight, three, and two, respectively. Results: Six out of eight patients with gastric cancer had positive results on both DWIBS/T2 and PET/CT. The diameter and depth of invasion of gastric cancer was larger in patients with positive DWIBS/T2 and PET/CT findings than those with negative findings. These results suggested that patients with gastric cancer with larger pixel numbers might tend to show positive results with DWIBS/T2. Conclusions: DWIBS/T2 and PET/CT have similar sensitivity for the diagnosis of upper gastrointestinal cancer. The diameter and depth of invasion affected the detectability of gastric cancer.
