Comparison of [⁶⁸Ga]Ga-DOTA-FAPI-04 and [¹⁸F]FDG PET/MRI in the Preoperative Diagnosis of Gastric Cancer

Figure 1

A 64-year-old male patient with gastric cancer diagnosed as gastric fundus tumor by gastroscopy. FDG-PET MRI showed a slight increase in FDG metabolism, with an SUVmax of 3.74 and no increase in metabolism in perigastric lymph nodes (A-D). FAPI-PET/MRI showed obvious thickening of the cardia, gastric fundus and lesser curvature of the gastric body, and an abnormal increase in FAPI uptake (arrow), with an SUV_max of 11.2 (E-H). Small lymph node shadows were detected behind the lesser curvature of the stomach and the pancreas, and there was no FAPI uptake.
