Fluoroscopy

Fluoroscopy is a type of x-ray that shows organs, tissues, or other internal structures moving in real time. Standard x-rays are like still photographs. Fluoroscopy is like a video.

It shows your body systems in action. These include the cardiovascular (heart and blood vessels), digestive, and reproductive systems. Fluoroscopy allows your health care provider to watch your organs or structures as they function, such as your heart beating, lungs inflating, or intestines moving food.

The procedure can help your provider evaluate and diagnose a variety of conditions.

Why this test is done

You may need a fluoroscopy if your provider wants to check the function of a particular organ, system, or other internal part of your body. You may also need fluoroscopy for certain medical procedures that require imaging guidance. This could include surgery or the placement of a stent.

How to prepare

Your preparation will depend on the type of fluoroscopy procedure. Your provider will let you know if you need to do any special preparations. For example, for certain procedures, you may be asked to fast (not eat or drink) for several hours before the test.

You may also need to avoid certain medicines before the test, so tell your provider about everything you take. But don’t stop taking any medicines unless your provider tells you to.
