Fluoroscopy (use of dye in X-ray)

What is fluoroscopy?

Fluoroscopy is a form of X-ray that enables the doctor to see internal organs and structures in motion. A contrast material (dye) may be introduced into the body through injection, swallowing or an enema. This dye allows the picture to be viewed clearly on a monitor or screen.

Types of fluoroscopic exams include:

Upper Gastrointestinal Series (Upper GI Series):

  • An examination of the pharynx, oesophagus, stomach, and first part of the small intestine
  • Barium Enema (Lower GI Series):

An examination of the large intestine

  • Hysterosalpingogram (Hystero):

An examination of a woman’s uterus and fallopian tubes

Preparing for Fluoroscopy

Upper GI Series:

  • Nothing to eat or drink after midnight

Lower GI Series:

  • You will receive instructions for a bowel preparation from the scheduling department when your exam is booked.


  • Your doctor will provide you with the appropriate instructions.
  • This procedure is best performed 1 week after menstruation but before ovulation to make certain that you are not pregnant during the examination.
  • Your doctor may order a pregnancy test before the exam.
  • There may be some minor spotting after the test. Patients should bring a pad to wear after the procedure.

Risks or Complications:

  • Minimal exposure to radiation.
  • You should always inform your doctor or X-ray technologist if you are or might be pregnant.

How long will a fluoroscopy procedure take?
