Fluoroscopy

This modality is used to image moving body structures. In fact, you could call fluoroscopy an X-Ray “movie.” A continuous x-ray beam is passed through the body part being examined, and is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail, such as blood traveling through a blood vessel, the diaphragm moving up and down, or food moving through the digestive tract.

A dye or “contrast material” that shows up on X-rays can be injected or swallowed during fluoroscopy to outline blood vessels or organs.
