What is a fluoroscopy exam? what should i expect?

A Dynamic study.: You should expect to drink a suspension of barium sulfate (sometimes flavored) and you will be asked to move to certain positions in order to obtain the best possible pictures of the esophagus, stomach, duodenum and small bowel, depending on which body parts your doctor wants evaluated. For a barium enema the contrast is inserted through a rectal tube and the colon is evaluated.
