A videofluoroscopic swallowing examination (VFSS) requires the use of radiopaque contrast media to make the bolus visible. Historically, there were no specific contrast agents designed for the oropharyngeal VFSS examination. This led to off-label practices where clinicians used barium designed for gastrointestinal imaging and prepared it in different consistencies, including mixing with food. We will discuss the importance of using standard barium and the risks that off-label mixing practices may have for altering exam results.

1. Contrast Media for VFSS

We will describe how contrast agents work and what the desirable properties of a contrast agent are for VFSS. We will discuss the difference between on-label and off-label use of barium.

2. Barium Concentration: How Does It Impact What We See on Videofluoroscopy?

We will discuss how altering the concentration of barium through methods like dilution can alter what you see on the exam and how this may influence VFSS exam results.

3. How Should I Choose Barium Products and Prepare Barium for VFSS?

We will discuss why it is important to understand manufacturer recommendations for preparing barium for use in VFSS and how off-label practices may influence the exam in undesirable ways.
