Fluoroscopy, or fluoro, is a medical imaging technique involving X-rays used to take real time video footage inside the body. Fluoroscopy creates an X-ray video recording to show the movement of a body part or organ.
It is used to guide procedures, such as implant placements, joint injections, cardiac catheterization or coronary stents. It is also used to check intestine and stomach function, such as a food swallowing study to assess how the throat and mouth muscles are working. Fluoroscopy may use a contrast dye to help the doctor see the blood vessels or tissues better.
