Nuclear Scintigraphy in Practice: Gastrointestinal Motility

Abstract

Objective: The purpose of this article is to describe the clinical utility of state-of-theart gastrointestinal transit scintigraphy, including the standardized esophageal transit, solid and liquid gastric emptying, small-bowel transit, colon transit, and whole-gut transit scintigraphy, with an emphasis on procedure performance.

Conclusion: Radionuclide gastrointestinal motility studies are noninvasive, quantitative, and physiologic diagnostic tools for evaluating patients with gastrointestinal complaints.

Keywords: esophageal transit; gastric emptying; gastrointestinal transit; gastroparesis; intestinal motility.
