Video Fluoroscopic Swallow Study for Adults

A Video Fluoroscopic Swallow Study (VFSS), also known as a Modified Barium Swallow (MBS), is a procedure a speech pathologist completes in order to evaluate the anatomy and physiology of the oral cavity, pharynx, and screening of the esophagus. This is an x-ray study which allows the speech pathologist to evaluate the patient’s swallow function. 

Patient Safety Tips Prior to a Diagnostic Exam in Radiology

• If you are pregnant or may be pregnant, please tell your doctor or technologist.
• Please leave your valuables at home or in your room in the hospital.
• Please let us now if you need interpreting services, this can be arranged for you.

Prepare for the Exam

• If you will only be completing a VFSS, a fast is not necessary but be aware you will be required to eat/drink.   
• If you will be completing an Esophagram in conjunction with a VFSS, your stomach must be empty of food. Therefore, your doctor will ask you not to eat solid food.

During the Exam:

• Depending on your mobility status, you will either sit in a special chair or stand next to the fluoroscopy (X-Ray) machine.  
• The speech pathologist will give you food of varying textures and liquids mixed with a white substance called barium for you to swallow; this allows them to view the food and liquid through x-ray during swallow. 
• The radiology technologist will operate the X-Ray machines to take pictures during your swallow. 

After the Exam

• If you are going home, you may resume normal activities.
• Drink plenty of fluids in the days following the exam.
