"Fluoroscopy is a study of moving body structures - similar to an x-ray "movie." A continuous x-ray beam is passed through the body portion being examined, and is transmitted to a TV-like monitor so that the body segment and its motion can be seen contained by detail."

Ultrasound could also show movement, such as you see a fetus moving during an OB ultrasound. BUT, the majority of organs seen on ultrasound do not really move. We can visualize the kidneys, liver, pancreas, gallbladder, spleen, for example, and they don't really "move". The gallbladder does contract when it empty bile, but we don't see the contracting motion when we are doing an ultrasound. The gallbladder appears full or it is contracted, period.
Fluoroscopy is used to evaluate the intestinal tract. For example, a barium swallow will allow the radiologist to keep under surveillance a patient's swallowing function. We can see the peristaltic movement of the stomach, as the barium moves from the esophagus to the stomach and out to the small bowel. Ultrasound cannot see through air, so it cannot visualize bowel, due to gas.
