Fluoroscopy is a non-invasive exam used to visualize your gastrointestinal tract in motion. Fluoroscopy uses a continuous x-ray beam to create a sequence of images that are projected onto a fluorescent screen, or television-like monitor.

When used with a contrast material, which clearly defines the area being examined by making it appear bright white, this special x-ray technique makes it possible for a physician to view internal organs in motion. Still images are also captured and stored digitally on a computer.
