Fluoroscopy is a type of medical imaging that shows a continuous x-ray image on a monitor, much like an x-ray movie. It is used to diagnose or treat patients by displaying the movement of a body part or of an instrument or dye (contrast agent) through the body.

During a fluoroscopy procedure, an x-ray beam is passed through the body. The image is transmitted to a monitor so that the body part and its motion can be seen in detail.

Fluoroscopy is used in many types of examinations and procedures. Some examples include:

• Barium x-rays and enemas (to view movement through the GI 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)
