Radiologic examination, swallowing function, with cineradiography/videoradiography

AI EXPLANATION: A barium swallow study, also known as an examination of swallowing function, is an imaging test that evaluates how effectively you move food and liquids from your mouth into your stomach. During the exam, you eat or drink substances mixed with barium, a safe compound that shows up clearly on continuous video X-rays. A specialist watches the moving images in real time to assess the muscles and structures of your mouth, throat, and esophagus, checking for swallowing difficulties, structural blockages, or liquid entering the airway.
