The diagnostic and prognostic role of combined [ 18 F]FDG and [ 68 Ga]-DOTA-peptides PET/CT in primary pulmonary carcinoids: a multicentric experience.

• Combination of [18F]FDG and [68Ga]-DOTA-peptides PET/CT results may help to differentiate between atypical and typical lung carcinoids. • The SUVmax ratio between [18F]FDG and [68Ga]-DOTA-peptides PET may help to differentiate between atypical and typical lung carcinoids. • Histotype and PET/CT features have a prognostic impact on PFS.
