Fluoroscopy and Barium X-Rays (Upper and Lower GI)
Fluoroscopy is the study of moving body structures, similar to 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.
Barium X-ray (Upper and Lower GI) is a radiographic examination used to diagnose abnormalities of the gastrointestinal (GI) tract. A barium enema exam also is known as a Lower GI, and a barium swallow exam also is known as an Upper GI.
Barium enema (Lower GI) involves filling the large intestine with diluted barium liquid while X-ray images are being taken. Barium enemas are used to diagnose disorders of the large intestine, colon, and rectum. These disorders may include colonic tumors, polyps, diverticula, and anatomical abnormalities.
Barium swallow (Upper GI) is an examination of the esophagus and stomach using barium to coat the walls of the upper digestive tract so that it may be examined under X-ray. Barium swallows are used to identify any abnormalities such as tumors, ulcers, hernias, pouches, strictures, and swallowing difficulties.
