indium In 111-pentetreotide
(IN-dee-um … PEN-teh-TREE-oh-tide)
A radioactive
drug used to find certain types of neuroendocrine tumors
(tumors that form from cells that release hormones). Indium
In 111-pentetreotide binds to a protein called somatostatin
receptor, which is found on some neuroendocrine tumor
cells. Indium In 111-pentetreotide builds up in these cells
and gives off radiation that can be detected by a scanner
to help show where the tumor cells are in the body.
