Octreotide scintigraphy

Octreotide scintigraphy uses 111In-labeled octreotide which is a somatostatin analog; it is also known as an OctreoscanTM, a brand name for 111In-labeled pentetreotide; pentetreotide is a DTPA-conjugated form of octreotide, originally manufactured by Mallinckrodt Nuclear Medicine LLC, which now forms part of Curium). 

It is particularly useful for assessment of neuroendocrine tumors, and the Krenning Score is used to grade these, most commonly for PRRT planning..

Examples include:

Certain non-neuroendocrine tumors can also show uptake in an octreoscan. Examples include:

Also, certain autoimmune or granulomatous diseases may occasionally show octreotide uptake.
