Fluoroscopy is a type of real-time X-ray imaging that creates moving pictures of the inside of your body, like watching a live video rather than taking a single photograph.

How it works: A continuous X-ray beam passes through your body, and the images appear instantly on a monitor, allowing doctors to see your organs and structures in motion.

Common uses:

• Guiding procedures like injections or catheter placements

• Swallowing studies to watch food move through your digestive system

• Joint injections for pain management

What you'll experience: You may be asked to move, change positions, or swallow contrast material while the doctor watches the live images on a screen. The procedure length varies depending on what's being done.
