Fluoroscopy is a real-time X-ray imaging procedure showing a continuous image on a monitor, according to the U.S. Food and Drug Administration. The procedure shows movement of a tool within the body, such as a catheter placed in the body.
The fluoroscopy technique works for diagnostics and to assist other medical procedures by allowing the physician to see inside the body as he performs the procedure, states Johns Hopkins Medicine. Contrast dye is sometimes part of the fluoroscopy procedure. Doctors use the procedure to watch the dye move through the body. The tool also allows doctors to look at multiple systems within the body at once. The patient typically lies on an X-ray table during the exam but may move to different positions to get different X-ray views.
