The fluoroscopy also uses X-ray to generate images. However, instead of getting a “picture” with X-ray, fluoroscopy is akin to getting a video with X-ray. Just as in regular video, motions and timed interactions between different entities can be visualized and analyzed. Usually when your doctor asks for a fluoroscopy, he or she is asking for evaluation of the gastrointestinal tract with enteric contrast material. Rarely, they may want to evaluate other motion sensitive abnormalities.
