The article discusses nuclear medicine imaging of neuroendocrine tumours (NETs), a clinically diverse group of tumours which commonly affect the gastroenteropancreatic tract and lungs. NETs comprise carcinoid tumours and various pancreatic tumours such as gastrinoma, insulinoma, VIPoma, glucagonoma and somatostatinoma. Functional imaging with indium-111-octreotide has better sensitivity than conventional imaging and detects increased expression of somatostatin receptors by tumors. New peptides with higher detection rates, labeled to positron emitting radionuclides, have been introduced for PET/CT imaging. Gallium-68-peptides PET/CT is the new gold standard in imaging NETs.
