F-FDG PET/CT is one of the most advanced diagnostic methods for lymphoma,which plays an important role in the diagnosis,efficacy evaluation,prognosis prediction and clinical decision-mak-ing of lymphoma.Radiomics,which uses complex bioinformatics methods to extract quantitative information from medical images to characterize tumor heterogeneity,has blossomed over the past decade.Radiomics has been applied to 18F-FDG PET/CT to quantify the heterogeneity within tumors,which has great potential and value in the study of lymphoma.This article reviews the research progress and application of 18 F-FDG PET/CT radiomics in lymphoma.
