What it means
Fluoroscopy is a real-time X-ray technique that produces continuous moving images of the inside of your body, similar to an X-ray movie. A contrast dye is often swallowed, injected into a joint, or administered through a catheter to make structures visible. The images appear on a monitor and allow the doctor to observe the movement of organs, blood vessels, or instruments during procedures such as catheter placement, barium swallow studies, or joint injections. You may need to fast beforehand depending on what is being examined. Radiation exposure is higher than a regular X-ray because the beam is continuous. Your radiology team uses protective shielding to minimize exposure. The procedure length varies widely by type.
