Fluoroscopy is an imaging technique that takes live X-ray images of the body by passing a continuous X-ray beam through the structure being studied. The X-ray images appear on a video screen in real time, which allows the radiologist to see how well the structure is functioning.
During a fluoroscopy exam, the patient ingests or is injected with a contrast agent. A continuous X-ray beam is then passed through the body and transmits the images to a monitor where the motion can be seen in detail.
This procedure can be used for:
- Barium x-rays and enemas (to view movement through the gastrointestinal tract)
- Catheter insertion (to direct the placement of a catheter during angioplasty or angiography)
- Blood flow studies (to visualize blood flow to organs)
- Orthopedic surgery (to view fractures and fracture treatments)
