Fluoroscopy is a technique for obtaining "live" x-ray images of a living patient. The radiologist uses a switch to control an x-ray beam that is transmitted through the patient.  The x-rays then strike a fluorescent plate that is coupled to an "image intensifier" that is (in turn) coupled to a television camera. The radiologist can then watch the images "live" on a TV monitor. Fluoroscopy is often used to observe the digestive tract (Upper GI series - Barium Swallow, Lower GI series or Barium Enema).

Flouroscopy is also used during many diagnostic and therapeutic radiologic procedures, to observe the action of instruments being used either to diagnose or to treat the patient.

How do you prepare for Fluroscope exams?
Preparation varies depending on the type of test. The contrast agent which allows the image to be viewed when x-rayed will be introduced into the body via swallowing, injection or an enema. Your doctor will give you specific instructions prior to your procedure.

How is Fluoroscopy Performed?
Fluoroscopy may be part of an examination or procedure that is done on either an outpatient or inpatient basis. The specific type of procedure or examination being done will determine whether any preparation prior to the procedure is required. Your physician should notify you of any pre-procedure instructions.

Although each facility may have specific protocols in place and specific examinations and procedures may differ, fluoroscopy procedures generally follow this process:

1. An intravenous (IV) line is started in the patient's hand or arm.
2. The patient is positioned on the x-ray table.
3. For procedures that require catheter insertion, such as cardiac catheterization or catheter placement, an additional line insertion site may be used in the groin, elbow, or other site.
4. A special x-ray scanner is used to produce the fluoroscopic images of the body structure being examined or treated.
5. A dye or contrast substance may be injected into the IV line in order to better visualize the structure being studied.
6. The type of care required after the procedure will depend on the type of procedure done. Certain procedures, such as cardiac catheterization, will require a recovery period of several hours with immobilization of the leg or arm where the cardiac catheter was inserted. Other procedures may require less time for recovery. The physician will give more specific instructions related to care after the examination or procedure.

What happens after the procedure?
Post-exam care depends on the type of procedure. Although most procedures require short recovery periods, in some cases you may have to remain in recovery for a few hours. If you have ingested barium, drink more water than usual in order to avoid constipation.

What are the benefits of fluoroscopy?
Unlike an x-ray, which shows a detailed yet static image, fluoroscopy allows a physician to see a live image of the body's internal organs in order to observe their size, shape and movement.

What are the risks of fluoroscopy?
Although radiation is minimal, there is the chance of skin injury due to radiation exposure, as well as the usual risks associated with radiation.
