Modified barium swallow is a study conducted in collaboration with radiology to observe the swallowing function of multiple consistencies from mouth to stomach. Minimal exposure fluoroscopy provides real-time opportunities to assess function and to determine the usefulness and safety of compensatory swallowing maneuvers to reduce or eliminate the swallowing problem. The use of real foods that are a problem for the patient means that the speech-language pathologist completing the study can observe swallowing problems that correspond to the patient history.
