How do you test for aspiration?

How is aspiration from dysphagia diagnosed?
  1. Modified barium swallow test (MBS). This can show if material is going into your lungs.

What happens during a fluoroscopy?

Fluoroscopy is a study of moving body structures--similar to an X-ray "movie." A continuous X-ray beam is passed through the body part being examined. The beam is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail.
