Synchronous bilateral bronchial carcinoid diagnosed with combined dual tracer (18F-FDG and 68Ga-DOTATOC) PET/CT scans

Evolving role of PET/CT with different tracers in the evaluation of pulmonary neuroendocrine tumours

“…Furthermore, 68 Ga-somatostatin analogues provided better results compared to the radiolabelled amino acid 18 Fdihydroxyphenylalanine (DOPA) in evaluating lung NETs [6], but literature reports specifically addressing the use of 18 F-DOPA in pulmonary NETs are few [11]. Since different information may be obtained using various PET tracers, some authors have recently reported preliminary results on dual-tracer PET/CT imaging using 68 Ga-somatostatin analogues and 18 F-FDG in well-differentiated pulmonary NETs [12][13][14][15]. A retrospective study by Kayani et al compared 68 Ga-DOTATATE and 18 F-FDG PET/CT findings in 18 patients with pulmonary NETs, including 13 BCs.…”
