Fluoroscopy allows doctors to obtain real-time moving images of the body.
The images are projected onto a monitor which allows constant monitoring of the examination.
Fluoroscopy is similar to an X-ray ‘movie’ and is often done while a contrast dye moves through the part of the body being examined.
A barium swallow test (cine esophagram, swallowing study, esophagography, modified barium swallow study, video fluoroscopy swallow study) is a special type of imaging test that uses barium and X-rays to create images of your upper gastrointestinal (GI) tract. Your upper GI tract includes the back of your mouth and throat (pharynx) and your esophagus.
Barium is used during a swallowing test to make certain areas of the body show up more clearly on an X-ray. The radiologist will be able to see size and shape of the pharynx and esophagus. He or she will also be able see how you swallow. These details might not be seen on a standard X-ray. Barium is used only for imaging tests for the GI tract.
A barium swallow test may be used by itself or as part of an upper GI series. This series looks at your esophagus, stomach, and the first part of the small intestine (duodenum).
A doctor can use fluoroscopy for any of the following reasons:
- Orthopedic surgery: Surgery concerned with musculoskeletal system conditions.
- Catheter insertion: Inserting a tube into the body.
- Blood flow studies: Visualizing the flow of blood to the organs.
- Enemas: Inserting a rubber tip into the rectum.
- Angiography: X-rays of lymph or blood vessels, including heart, leg and cerebral vessels.
- Urological surgery: Surgery of the urinary tract and sex organs.
- Pacemaker implantation: Implanting a small electronic device in the chest
