Diagnostic value of PET imaging features multi-parameter model for prognosis of non-Hodgkin lymphoma
Objective:Analysis of fluorine-fluoro deoxidization glucose(f-18 fluorodeoxyglucose,18 f-FDG)type positron emission computed tomography(ct)imaging(positron emission tomography/computed tomography,The diagnostic value of multi-parameter models of PET/CT imaging features in prognostic assessment of patients with non-Hodgkin's lymphoma.Methods:A total of 80 patients with non-Hodgkin lymphoma who were clinically diagnosed in our hospital from May 2021 to August 2022 were selected as the study subjects.All patients received chemotherapy and were analyzed by CT,18F-FDG PET/CT scan after treatment.The diagnostic value of 18F-FDG PET/CT was analyzed with pathological diagnosis as the gold standard.To analyze the diagnostic value of each metabolic parameter to the prognosis of patients.Results:CT scan,the positive diagnosis rate was 67.50%.The positive diagnosis rate of 18F-FDG PET/CT scan was 67.50%,and there was no significant difference between the two methods(P>0.05).The specificity,sensitivity,accuracy and positive predictive value of 18F-FDG PET/CT method were significantly higher than those of conventional CT scanning method(P<0.05).Among the PET/CT parameters,total glycolysis volume and tumor metabolic volume could be used as the influencing conditions for progression free survival(PFS)(P<0.05).The Eastern United States Tumor Collaborative Group score(P<0.05)can be used as a prognostic condition for PFS in patients with non-Hodgkin lymphoma.Conclusion:18F-FDG PTE/CT imaging is highly accurate in evaluating the efficacy of chemotherapy in patients with non-Hodgkin lymphoma.
