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:  

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.
