Modified Barium Swallow Study
Also written as: MBSS — Modified Barium Swallow Study
Dynamic radiographic examination assessing all phases of swallowing function using barium-coated materials of varying consistencies.
Full Definition
The Modified Barium Swallow Study (MBSS) is a fluoroscopic examination that provides real-time visualization of the swallowing process from oral preparation through esophageal clearance. Also known as videofluoroscopic swallow study (VFSS), this procedure uses various consistencies of barium-coated foods and liquids to identify the anatomical and physiological aspects of dysphagia. The MBSS allows for assessment of aspiration risk, identification of compensatory strategies, and determination of safe diet textures and liquid consistencies for patients with swallowing disorders.
Usage
Usage note: Capitalize all major words when writing the full term. MBSS is the preferred abbreviation over VFSS in many clinical settings.
