A videofluoroscopic swallow study (VFSS) is a medical test that evaluates how well a person swallows. During the procedure, the patient consumes a small amount of food or liquid mixed with a safe radiopaque contrast agent while X-ray images are taken. This allows healthcare professionals to observe the swallowing process in real-time and identify any issues. The VFSS is commonly used to diagnose swallowing disorders, known as dysphagia, which can lead to complications like choking or aspiration. By analyzing the X-ray images, specialists can develop appropriate treatment plans to improve swallowing safety and efficiency for the patient.
