In Crohn’s Disease A Case Of False Positive Octreoscan

Neuroendocrine tumors, such as carcinoid tumors, overexpress somatostatin receptors in their membranes. Octreotide is an analogue whose molecule is a shortened version of somatostatin’s with a high affinity for these receptors. The labelled form of octreotide is able to be imaged in scans (Octreoscan) and, therefore, pathological conditions overexpressing somatostatin receptors are easily recognized in this technique.
