Localization of neuroendocrine tumours with~111 InDTPA- octreotide scintigraphy (Octreoscan): a comparative study with CT and MR imaging

摘要

A wide variety of neuroendocrine tumours express somatostatinreceptors, and can be visualized by radiolabelled somatostatinanalogue scintigraphy. To investigate the value of [~111In]-octreotide scinti- graphy (Octreoscan), 48 patients (37 withproven cacinoid, pancreatic endocrine and medullary car- cinoma ofthyroid tumours, 11 with neuroendocrine syndromes multiple endocrineneoplasia (MEN-I) and Zollinger-Ellison syndrome(ZES) were examinedwith ~111In - DTPA - D - Phe~1 - octreotide.
