Multiple metabolic parameters and visual assessment of 18 F-FDG uptake heterogeneity of PET/CT in advanced gastric cancer and primary gastric lymphoma

Conclusion18F-FDG PET/CT had a high diagnostic efficiency for discrimination of AGC and PGL, especially between DLBCL and other pathological subtypes. Visual assessment used to evaluate18F-FDG uptake heterogeneity could help to distinguish the two types of tumors. In addition, our innovative method of measuring the heterogeneity of18F-FDG uptake —namely, SUVmax-d—could contribute to identification of the two tumor types and should have its significance clarified by future studies.
