                                        18 F-fluoro-2-deoxyglucose (FDG)-based positron emission tomography (PET)/computed
                                        tomography (CT) is an indispensable tool in modern oncology, extensively used for
                                        diagnosing and staging various cancers.  The maximum standardized uptake value
                                        (SUV ) of FDG helps identify the most metabolically active areas of disease.  In

                                        2019, we compared SUV max  for different cancer types and determined the effect of
                                        demographic, pathological, and clinical variables on SUV max . The study included 117
                                        newly diagnosed cancer patients who underwent FDG PET/CT before treatment. Data
                                        on descriptive variables, including age, gender, stage, histopathological diagnosis,
                                        and tumor differentiation grade, were collected for each patient. Correlation analysis
