These findings inform potential impairments that may be seen during the second part of the FEES protocol. The second part of the FEES protocol involves food, or "bolus" presentation to observe swallow function. [9] Food coloring is typically given in the food to track the food as it travels along the natural pink-colored tissues of the throat ...
An upper gastrointestinal series, also called a barium swallow, barium study, or barium meal, is a series of radiographs used to examine the gastrointestinal tract for abnormalities. A contrast medium , usually a radiocontrast agent such as barium sulfate mixed with water, is ingested or instilled into the gastrointestinal tract, and X-rays are ...
The use of barium during pregnancy is safe for the baby; however, X-rays may result in harm. [4] Barium sulfate suspension is typically made by mixing barium sulfate powder with water. [1] It is a non-iodinated contrast media. [5] Barium sulfate has been known since the Middle Ages. [6] In the United States it had come into common medical use ...
Barium sulfate, an insoluble white powder, is typically used for enhancing contrast in the GI tract. Depending on how it is to be administered the compound is mixed with water, thickeners, de-clumping agents, and flavourings to make the contrast agent.

The barium sulfate, a radiodense (shows as white on X-ray) contrast medium, flows through the rectum into the colon. A large balloon at the tip of the enema tube may be inflated to help keep the barium sulfate inside. The flow of the barium sulfate is monitored by the health care provider on an X-ray fluoroscope screen (like a TV monitor). Air ...
A protocol describes what types of people may participate in the trial; the schedule of tests, procedures, medications, and dosages; and the length of the study. While in a clinical trial, participants following a protocol are seen regularly by research staff to monitor their health and to determine the safety and effectiveness of their treatment.
