Fluoroscopy

With the aid of a contrast agent, fluoroscopy enables an x-ray technologist to capture an image of an internal body organ in “real time,” while it is functioning. The contrast agent allows the image to be viewed clearly on a monitor or screen.

What are some common uses of fluoroscopy?

Fluoroscopy is used to screen for ulcers, benign tumors (polyps, for example), cancer, or signs of certain other intestinal illnesses.

Before:

  • You should inform your doctor about any recent illnesses or other medical conditions, as well as any allergies you might have to medications
  • Women should always inform the technologist if there is any possibility that they are pregnant
  • Small Bowel Series (this exam may take up to four hours): Nothing to eat or drink after midnight the night before

Upper G.I. or Esophogram

  • If your appointment is before 1:00 p.m.:
    • Nothing to eat or drink after midnight the night before
  • If your appointment is after 1:00 p.m.:
    • Nothing to eat or drink six to eight hours prior to your appointment.

Barium Enema

A barium enema requires thorough cleansing of your colon. You must come in to pick up a prep kit at least three days before your exam date. It is important that you drink plenty of clear liquids during the prep and follow all instructions.

IVP (Intravenous Pyelogram)

  • If your appointment is before 1:00 p.m.:
    • Clear liquids only on the day before your exam. Examples of a clear liquid include: coffee, tea, soda, water, gelatin, broth, hard candy, sports drink (such as Gatorade), popsicle and juice without pulp.
  • If your appointment is after 1:00 p.m.:
    • On the day before your exam, you may have a light breakfast before 10:00 a.m.  Following 10:00 a.m., clear liquids only.
  • At 2:00 p.m., ingest 2 oz. (4 Tbs.) castor oil or one full bottle of citrate of magnesium. Continue on a clear liquid diet only until appointment time. Examples of a clear liquid include: coffee, tea, soda, water, gelatin, broth, hard candy, sports drinks (such as Gatorade), popsicle and juice without pulp.

During:

  • Fluoroscopy is generally painless
  • Depending on the type of fluoroscopic test you undergo, you will be asked to lie or stand between the x-ray machine and a fluorescent screen after putting on a gown
  • An x-ray scanner produces fluoroscopic images of the body part being examined
  • You may be re-positioned frequently to enable the radiologist or technologist to capture different views
