O

OctreoScan (Somatostatin Receptor Scintigraphy) Imaging

Many gastrointestinal endocrine tumors have receptors for somatostatin, a hormone that is produced naturally by the body that suppresses the response to hormones involved in growth, metabolism, and digestion. Patients suspected of having a gastrointestinal carcinoid or pancreatic endocrine tumor receive an injection of a synthetic form of somatostatin that is attached to a radioactive substance. Radiation-sensitive imaging tests reveal whether there are any focal spots indicating the presence of an endocrine tumor - similar to an MIBG scan.

Oropharyngeal Motility (swallowing) Study

Also called a modified barium swallow test, this procedure is used to evaluate difficulty in swallowing. The patient is given small amounts of a liquid containing barium to drink with a bottle, spoon, or cup. Barium is a metallic, chemical, chalky, liquid used to coat the inside of organs so that they will show up on an x-ray. a series of x-rays are taken to evaluate what happens as the liquid is swallowed.
