Analysis of theApplication Value of Standardised Uptake Valueof 18F-FDG PET/CT in the Diagnosis of Local Recurrence of Primary Liver Cancer
Objective:To explore the application value of standardized uptake value(SUV)of 18F-FDG PET/CT in the diagnosis of local recurrence of primary liver cancer.Methods:The clinical data of 100 patients with suspected local recur-rence of primary liver cancer in our hospital from March 2021 to April 2022 were analyzed retrospectively.All patients were examined by 18F-FDG PET/CT,and pathological examination was performed one week after the examination.To analyze the application value of SUV=2.5 as the quantitative diagnostic standard of PET in the diagnosis of local recur-rence of primary liver cancer,and to distinguish the diagnostic efficacy of local recurrence and non-recurrence of primary liver cancer by using different quantitative indexes of PET.Results:Among the 100 patients,25 cases were diagnosed as lo-cal recurrence of non-primary liver cancer and 82 cases as local recurrence of primary liver cancer.When SUV=2.5 is used as the cutoff value for quantitative diagnosis of PET,the sensitivity is 94.67％,the specificity is 88.00％,the Jordan index is 0.29,and Kappa is 0.28.Conclusion:SUV=2.5 of 18F-FDG PET/CT has high application value in the diagnosis of local recurrence of primary liver cancer.
