A gastric emptying study is a nuclear medicine study which provides an assessment of the stomach's ability to empty.It may be used if there are complications after gastric surgery, for gastric reflux, or suspected gastroparesis amongst other indications. [1]
Because stomach emptying is the testing process's rate-limiting step, the amount of 13CO2 present in an exhaled breath test represents gastric emptying. Every 30 minutes, post-meal breath samples are collected and analyzed using isotope-ratio mass spectrometry. For a total of 4–6 hours, samples are collected every 30 minutes. [39]
A gastric emptying study is considered the gold standard to assess the gastric emptying rate. [47] A large number of studies have indicated that most cases of peptic ulcers, and gastritis, in humans are caused by Helicobacter pylori infection, and an association has been seen with the development of stomach cancer.

A gastric emptying scintigraphy test involves eating a bland meal that contains a small amount of radioactive material. An external camera scans the abdomen to locate the radioactive material. The radiologist measures the rate of gastric emptying at 1, 2, 3, and 4 hours after the meal. The test can help confirm a diagnosis of dumping syndrome.

For barium follow-through examinations, a 6-hour period of fasting is observed prior to the study. [10] Barium is administered orally, sometimes mixed with diatrizoic acid (gastrografin) to reduce transit time in the bowel. Intravenous metoclopramide is sometimes also added to the mixture to enhance gastric emptying.
