What is a Modified Barium Swallow Study?
- A modified barium swallow is type of X-ray done under Fluoroscopy with collaboration of a Speech Pathologist The purpose of the study is to take pictures of the throat, such as the trachea and windpipe, to see how your child swallows.
- The study helps the doctor see if food or liquid is going into the airway after being swallowed.
- During the test, your child will be asked to eat and drink different types of textured food and drinks such as cookies and apple sauce that is mixed with a special substance called “barium”.
- Barium acts as a highlighter to allow the doctor to see the movement of the food through the esophagus.
- The x-ray takes between 30 minutes to one hour, depending on how well your child cooperates during the test.
- A Nicklaus Children’s Hospital staff member will call you ahead of time with details and instructions on how to prepare for the test including what kinds of foods to bring the day of the exam and the specific amount of time your child may not eat before the exam.
What to Expect the Day of the Exam

Step 2: Taking Pictures
- A staff member of the Radiology Department will walk you from the waiting room to the X-ray room.
- Once in the X-ray room, you will see a camera attached to a long table with a video screen behind it.
- The table will be positioned in an upright/downside position. A chair will be placed next to the table where your child will be safely secured and sitting in during the pictures.
