A type of X-ray that produces images of your tissues and organs in real-time.

Fluoroscopy is a study of moving body structures, sort of like an X-ray “movie”. A continuous X-ray beam is passed through the body part being examined. The beam is transmitted to a monitor so that the body part and its motion can be seen in detail.

Fluoroscopy may be performed to evaluate specific areas of the body, including the bones, muscles and joints, as well as solid organs, such as the heart, lung, or kidneys. They are also used to examine the digestive system with a barium enema (a contrast material used to create clearer images of your digestive system).

Fluoroscopy may be used alone as a diagnostic procedure, or it may be used in conjunction with other diagnostic or therapeutic media or procedures.


Prior to the test, you will receive specific instructions and/or medicine to help cleanse your colon. Please inform your healthcare professional if you are allergic to barium or latex.

You may be asked to change into a patient gown. Please remove all piercings and leave all jewelry and valuables at home.


The radiologist performing the examination will begin by inserting barium into a tube that is inserted into your rectum. As the barium fills your colon, air will also be injected slowly to inflate it.

You will then be positioned on the X-ray table. Depending on the type of procedure, you may be asked to assume different positions, move a specific body part, or hold your breath at intervals while the fluoroscopy is being performed.

The X-ray will be used to produce the fluoroscopic images of the body structure being examined or treated. Once the images are taken, the rectal tube is removed, and you will be able to expel the barium in the washroom. Additional images may be required afterwards.

The testing will take approximately 30 minutes.


You may experience fatigue after the test, so you may need to arrange for transportation from the examination.

Drink extra fluids after the test to avoid dehydration.
