What to expect for your child's Modified Barium Swallow Study

A Modified Barium Swallow Study (MBSS) is a test that captures real-time video of your child's swallowing function while they eat and drink. An X-ray and a contrast liquid called barium are used during the exam. Your child will consume the barium during the test, allowing us to evaluate their swallowing function and check for aspiration (when food or drink enters the airway). A Speech-Language Pathologist (SLP) and a Radiologist will assist with the exam.

During the test, you are welcome to help feed your child and keep them comfortable, provided there is no chance you are pregnant. The procedure typically takes about 15 to 30 minutes. Afterward, your child can usually resume their regular activities and eating habits unless the doctor advises otherwise.

What should you do prior to the exam?

Your child will need to have an empty stomach for the MBSS. Please refrain from feeding your child for 2 hours prior to the exam. Dress your child comfortably in clothes that are easy to remove. Try to avoid clothing with snaps, buttons, or zippers.

Please bring any bottles or cups that your child drinks from, so we can use them during the exam. In addition, bring any foods that your child enjoys eating or has difficulty with. You are also welcome to bring a familiar toy to comfort your child.

Parents are welcome to accompany their child into the exam room. However, arrangements should be made for siblings to be cared for elsewhere. For the safety of pregnant women or those who may be pregnant, they will be asked to leave the exam room during the procedure. Please ensure that someone else is available to accompany your child if necessary.

Please arrive 15 minutes prior to your appointment time to allow for check-in and paperwork completion.

What should you expect during the exam?

The SLP will ask questions about your child's medical history and any concerns you may have. Then, the SLP will explain the procedure to both you and your child.

Your child will be seated in a small chair next to the X-ray machine, where they will eat and drink barium in different consistencies (e.g., thin liquids like water, purees like pudding). The barium will be visible on the X-ray screen.

 

 

 

 

 

What should you expect after the exam?

If your child has a bowel movement after the exam, it may appear white or grayish — do not be alarmed! The barium can cause this discoloration. Please note that barium has no nutritional value.

Exam Results

The images from your child's exam will be interpreted on the same day, and a report will be sent to your physician's office.
