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

摘要

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