Gastric Half Emptying Time for Gastric Emptying Scintigraphy …

WebJun 11, 2024 · Gastric emptying tests To see how fast your stomach empties its contents, one or more of these tests may be recommended: Scintigraphy. This is the most important test used in making a diagnosis of gastroparesis. It involves eating a light meal, such as eggs and toast, that contains a small amount of radioactive material. WebAbstract. Gastric emptying is the process by which the contents of the stomach are moved into the duodenum. This is accomplished by three mechanisms: (1) Peristaltic waves, (2) systolic contractions of the antrum, and (3) reduction in size of the stomach. Liquids will ordinarily empty faster than solids, and smaller objects faster than larger.
