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 ]
gastric mucosa imaging for Meckel's diverticulum (especially in pediatrics). Examples of radionuclide therapeutic procedures are 131 I treatment of hyperthyroidism, 131 I treatment of thyroid cancer, and; radioimmunotherapy with 90 Y ibritumomab tiuxetan (Zevalin) & 131 I tositumomab (Bexxar) therapy of low-grade non-Hodgkin's lymphoma.
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.
Gastroparesis (gastro- from Ancient Greek γαστήρ – gaster, "stomach"; and -paresis, πάρεσις – "partial paralysis") is a medical disorder of ineffective neuromuscular contractions (peristalsis) of the stomach, resulting in food and liquid remaining in the stomach for a prolonged period of time.
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.

Gastroparesis (delayed gastric emptying) may occur and is due to metabolic causes (e.g. poorly controlled diabetes mellitus), decreased gastric motility (e.g. due to head injury) or pyloric obstruction (e.g. pyloric stenosis). Delayed gastric emptying usually only affects the emptying of the stomach of high-cellulose foods such
Intravenous metoclopramide is sometimes also added to the mixture to enhance gastric emptying. [ 17 ] 600 ml of 0.5% methylcellulose can be given orally, after barium meal is given, to improve the images of small bowel follow-through by reducing the time taken for barium to pass through the small intestines, and increase the transparency of the ...
The proportion of dyspeptic individuals with delayed stomach emptying varies from 20% to 50%, depending on the study. [22] [23] In response to gastric balloon distension during fasting and following meal intake, patients with functional dyspepsia demonstrate impaired proximal stomach accommodation.
