2023年7月31日 · For the detection of pancreatic neuroendocrine tumors, an octreotide scan has a sensitivity of 75 to 100%. Octreotide is a synthetic analog of somatostatin, which is an endogenous peptide released by neuroendocrine cells, activated immune cells, and various inflammatory cells.

Tumor differentiation can be used to guide selection of nuclear imaging modalities for staging gastrointestinal and pancreatic NETs. Octreoscan appears more sensitive than (18)FDG-PET for well-differentiated NETs, whereas (18)FDG-PET demonstrates superior sensitivity for poorly-differentiated NETs.

Molecular imaging with radiolabeled somatostatin analogues [111 In-Pentetreotide (octreoscan)/ 68 Ga-DOTATOC PET/CT/etc.] is increasingly used for suspecting and the diagnosis of panNET in patients with a pancreatic mass [14, 132]. Imaging is used to establish the location of the primary panNET.

Endoscopic ultrasound (EUS) (A), arterial-phase of the dynamic contrast-enhanced computed tomography (CT) (B) and somatostatin receptor (SSR) scintigraphy with Octreotide (OctreoScan) (C, D) in a patient with a 1.5 cm, accidentally identified hypervascular pancreatic neuroendocrine tumor during CT angiography of the aorta (not shown).

The study describes the results of Octreoscan SPET (OCTSPET) qualitative and semi-quantitative evaluation in 38 patients with suspected pancreatic neuroendocrine tumors. SPET studies were acquired at 4 and 24 hours after the injection of 111-220 MBq of 111-In-pentetreotide (Octreoscan).

2025年1月11日 · This update aims to equip clinicians, radiologists, and researchers with the most recent knowledge and tools to enhance the diagnosis, treatment, and overall care of patients with pancreatic neuroendocrine tumors.

Pancreatic neuroendocrine neoplasms (panNENs) are heterogeneous neoplasms with neuroendocrine differentiation that show characteristic clinical, histomorphologic, and prognostic features; genetic alterations; and biologic behavior.

2024年12月10日 · pancreas (~8%) carcinoid tumors of the lung (~25% of all carcinoids) bronchial carcinoid ... has shown improved accuracy for detection of neuroendocrine tumors relative to indium-111 pentetreotide (Octreoscan) SPECT/CT 13,14. indium-111 octreotide (e.g. Octreoscan) SPECT-CT 15. iodine-123 MIBG will also concentrate on carcinoid tumors ...

Pancreatic neuroendocrine tumors (NET) have diverse clinical presentations. Patients with symptoms of hormone secretion may require specific medical interventions to control those symptoms prior to antitumor intervention. ... 111 Indium-DTPA-octreotide (Octreoscan™) has been commonly used, often in combination with cross-sectional imaging, to ...
