Step-by-step explanation:
The medium of choice for gastrointestinal tract contrast studies is a suspension of barium sulfate. When swallowed, this substance, sometimes referred to as a "barium milkshake," .
coats the intestinal tract and provides a contrast that is opaque to X-rays, allowing for greater visual detail in medical imaging. This method is essential for diagnosing various conditions such as acid
reflux disease, Crohn's disease, ulcers, and it is also utilized for assessing the structural abnormalities of the gastrointestinal tract.
In addition to barium sulfate, for assessing the normal function of the gastrointestinal tract such as absorption, other substances like radioactive fatty acids.
iron (59Fe), and vitamin might be administered orally. These compounds are then tracked in the body using different imaging techniques to provide data about the organ's functionality.
