GIT (Gastrointestinal Tract)
These are dynamic studies to evaluate the oesophagus, stomach, duodenum, small bowel and the large bowel. Both structure and function is thus evaluated.
Use is made of oral contrast material which is usually Barium. Occasionally water-soluble oral contrast agents are used such as Hexabrix or Gastrograffin are used. This is if there is a suspected abnormal connection between the oesophagus and the airway or if there is a chance of aspiration.
Fluoroscopy is used to obtain multiple images which can be reviewed. Due to the use of x-rays, female patients must make sure they are not pregnant.
