Overview

Other Imaging Findings

Octreoscan

The diagnostic procedure that utilizes a somatostatin analog is the OctreoScan, also called somatostatin receptor scintigraphy (SRS or SSRS): a patient is injected with octreotide chemically bound to a radioactive substance, often indium-111; for those patients whose tumor cells are avid for octreotide, a radiation-sensitive scan can then indicate the locations of the larger lesions.

An OctreoScan is a relatively crude test that generates subjective results.
