The gastroesophageal reflux scan is a nuclear scan that uses tiny amounts of radioactive material, or radioisotope, to take pictures of parts of the upper gastrointestinal (GI) tract. The patient drinks formula or milk mixed with sulfur colloid. The sulfur colloid gives off signals. A special camera and computer is used to take images of the sulphur colloid as it travels through the intestinal tract.
The gastroesophageal reflux scan is helpful in determining whether some of the formula or milk/sulfur colloid ends up in the lungs (aspiration) or whether there is any reflux of stomach contents in the throat. It may also be helpful in determining how long milk sits in the stomach.
