摘要
^(68)Ga-DOTA-peptide PET/CT is a recommended imaging modality in the workup of neuroendocrine neoplasms(NENs),which shows high diagnostic sensitivity and is a strong predictor of successful somatostatin receptor directed treatments.Although not routinely recommended,reliable evidences show that^(18)F-FDG PET/CT can provide complementary information in this setting with the ability to discriminate slow-proliferating tumors from aggressive,rapidly-proliferating tumors.Further,it has been proposed as an independent prognostic factor for the prediction of either overall survival or progression free survival.In this review,we provide insight into the biologic significance of ^(68)Ga-DOTA-peptides and ^(18)F-FDG uptake,and of the use of double tracer(^(68)Ga-DOTA-peptides plus ^(18)F-FDG)PET/CT in the clinical evaluation of patients affected by NENs.
