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.
PET-CT Scan
A gallium-68 receptor PET-CT, integrating a PET image with a CT image, is much more senstitive than an OctreoScan, and it generates objective (quantified) results in the form of a standardized uptake value (SUV).
