During the study, patients are asked to ingest an egg sandwich containing a radioactive substance (for example, technetium) that can be followed by a special camera. The emptying of the material from the stomach is then followed.
In a gastric emptying scan, abnormalities may include delayed gastric emptying (gastroparesis) or accelerated gastric emptying. Delayed emptying is characterized by prolonged retention of food in the stomach, often indicating conditions like diabetes or gastric outlet obstruction. Accelerated emptying may result from conditions like dumping syndrome, where food moves too quickly into the small intestine. These abnormalities can be assessed by measuring the percentage of food remaining in the stomach at set intervals post-ingestion.

A brain scan after a head trauma is nearly always done without contrast, because bleeding also shows up white on the scan. The scan should be done as quickly as possible with the shortest scan time because patients with head injuries are often restless. If there is a suspected neck injury, the patients head will have be scanned in the position it is in, and the patient can not be moved into the 'head box'. After the scan, both brain and bone setting views should be looked at to establish if there are any fractures.

Accelerated emptying may result from conditions like dumping syndrome, where food moves too quickly into the small intestine. These abnormalities can be assessed by measuring the percentage of food remaining in the stomach at set intervals post-ingestion.
The study is used most frequently to evaluate patients who have symptoms suggestive of decreased, delayed, or rapid gastric emptying, and no visible abnormality to explain their symptoms.
The value is expressed as a percentage of emptying over a period of time. For a technetium-filled egg sandwich, normal emptying is 78 minutes for half the material to leave the stomach, with a variation of 11 minutes.
GES scan studies that show emptying of the stomach in a longer than accepted period is abnormal. Severity of test results and symptoms do not always match; therefore, the physician must carefully interpret these findings. Diabetic.
The average gastric emptying time in dogs is typically around 2-6 hours.
The following factors decrease gastric emptying time:HungerAnxietyBody position of lying on the right sideHyperthryoidismIntake of fluids and antiemetic drugs

Reduce gastric acid secretion. Also causes faster emptying of liquids from the stomach, but delayed emptying of solids from the stomach. Source: medical doctor
