PET/CT using 18F-FDOPA provides improved staging of carcinoid tumor patients in a Canadian setting

AIM: In Canada, staging of carcinoid tumors is largely based on computed tomography (CT) imaging sometimes complemented with somatostatin receptor scintigraphy (SRS). This study assessed the diagnostic accuracy of 6-[¹⁸F]fluoro-3,4-dihydroxyphenylalanine (¹⁸F-FDOPA) PET/CT in neuroendocrine tumors. METHODS: We prospectively included 27 patients with either suspected carcinoid (n=6, with all prior tests negative) or with an established diagnosis …
