Excerpt
Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms of neuroendocrine origin. The majority of gastro-entero-pancreatic and bronchopulmonary NETs overexpresses somatostatin receptors. Ga-68-DOTA(0)-Phe(1)-Tyr(3)-octreotide (Ga-68-DOTATOC) is a Ga-68-labeled somatostatin receptor analog. Ga-68-DOTATOC PET/CT combines somatostatin receptor imaging with a computed tomography (CT) scan and is used for diagnosing, staging, and restaging of NETs. Arterial hyperperfusion using contrast-enhanced CT and ultrasound have previously been reported to characterize both metastasis from NETs and primary NETs. …
