What is a nuclear gastric emptying test?
A gastric emptying scan is a test that shows how quickly food leaves your stomach. This type of test is called a nuclear scanning test. A radioactive tracer is added to a solid meal that you eat. This tracer shows up on pictures taken by an external camera.
What radiopharmaceutical is used for gastric emptying?
For gastric emptying, an administered activity of 18.5 to 74 MBq (0.5-2 mCi) is generally used as a radiolabel for liquid and solid meals in adults. The affinity of this radiopharmaceutical for the protein matrix of egg whites facilitates the egg white labeling as the solid phase component of the meal [17].
What is scintigraphy for gastroparesis?
A gastric emptying scan (GES) is a medical test. It is also called a gastric emptying study or gastric emptying scintigraphy. The test is used to diagnose digestive conditions. A gastric emptying study is a nuclear medicine test, meaning it uses small amounts of radiation.
What is a 4 hour gastric emptying study?

Your doctor may order the scans if you frequently vomit, feel bloated after eating, or complain of abdominal pain.
What Radiopharmaceuticals are used for dual trace gastric emptying study?
Tc-99m MAA and other particulate radiopharmaceuticals may be used for gastric emptying studies which could be more practical in routine conditions.
What does abnormal gastric emptying mean?
Abnormal results mean your stomach takes longer to empty than normal. There are many reasons for abnormal results. For example, you might have a: Blockage between the stomach and the small intestine. Condition called gastroparesis, which means your stomach empties more slowly.

What is radionuclide scintigraphy?
A procedure that produces pictures (scans) of structures inside the body, including areas where there are cancer cells. Scintigraphy is used to diagnose, stage, and monitor disease. A small amount of a radioactive chemical (radionuclide) is injected into a vein or swallowed.
