Fluoroscopy

Also known as: continuous X-ray imaging.

What is Fluoroscopy?

An easy way to understand fluoroscopy is to think of it like an X-ray video. Instead of producing a static image of the inside of the body, fluoroscopy produces a continuous, moving image to show how structures within the body are moving.

What happens during the procedure?

The procedure is similar to an X-ray in that a part of the patient’s body is exposed to an X-ray machine. Except the machine produces a continuous image that is transmitted to a nearby television screen for monitoring and observation.

Is any special preparation needed?

The following fluoroscopy procedures require an appointment and almost all of these studies require advance preparation:  

  • Barium Swallow or Esophagus and Upper GI or Upper GI and Small Bowel
  • Cystogram or Voiding Cystourethrogram
  • IVP and Barium Enema
  • Barium Enema with Air Contrast
  • Gall Bladder Preparation

What are the risk factors?

Some small risks are related to the radiation exposure caused by fluoroscopy. But in general, the benefits of the procedure far outweigh the risks.
