Scintigraphy for measuring gastric emptying of solids in 4 hours is a medical test used to assess the speed at which solid food empties from the stomach and passes into the small intestine. During the test, the patient is given a small amount of solid food labeled with a radioactive material. Images are then taken of the amount of radioactive material present in the stomach at regular intervals over a period of 4 hours.
The test is used to diagnose gastric emptying disorders, such as gastroparesis, which is a condition in which the stomach does not empty properly, which can cause nausea, vomiting, abdominal pain, and other gastrointestinal symptoms.
The test is safe and noninvasive. The radioactive material used in the test is low-dose and is eliminated from the body within a few hours. Patients may need to follow certain instructions before the test, such as refraining from food and liquids for a specific period of time before the test. It is important to inform your doctor if you are pregnant or breastfeeding before undergoing the test.
