Fluoroscopy is a 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.
Fluoroscopy is used in many types of examinations and procedures such as:
- Barium X-rays– fluoroscopy allows the physician to see the movement of the intestines as the barium moves through them
- Cardiac catheterization– fluoroscopy enables the physician to see the flow of blood through the coronary arteries in order to evaluate the presence of arterial blockages.
- Intravenous (IV) catheter insertion– fluoroscopy assists the physician in guiding the catheter into a specific location inside the body.
During a fluoroscopy procedure, an X-ray beam is passed through the body. The image is transmitted to a monitor so the movement of a body part (esophagus, stomach, small intestine, colon, coronary artery, heart) or of an instrument or contrast agent (“X-ray dye”) through the body can be seen in detail.
