What is a Fluoroscopy Procedure?

Fluoroscopy is a tool which helps the Radiologist “see” inside the human body.  The physician is able to examine a patient’s vascular system, anatomical structures, and organs with the aid of fluoroscopy.

Fluoroscopy exams include but are not limited to, VCUG, Upper GI, Barium Swallow, Small Bowel Follow-through, Cystogram, Barium Enema exams.

Before my Fluoroscopy Exam appointment

  • Do not wear clothing with metal zippers, belts or buttons.

  • If your study requires consumption or administration of barium sulfate it is recommended that you mildly increase your fluid intake after the exam.


    Barium Sulfate is a dense and inert (not chemically reactive) product that will remain within the gastrointestinal tract in trace amounts.

    Dependent upon a patient’s motility a mild laxative could be helpful with the evacuation of residual barium sulfate. Consult your physician prior to using any laxative, it may cause dehydration.

During my visit

A majority of GI (gastrointestinal) studies such as esophagram, Upper GI Small Bowel Follow-through and other gastrointestinal procedures will be performed within 60 minutes.

Most GU (genitourinary) studies such as Cystograms, VCUG, RUG (Retrograde Urogram) and other Genitourinary imaging procedures will be performed within 60 minutes.

Lower GI (gastrointestinal) procedures, such as Barium Enema, require at least 90 minutes.

There are no limitations after your Fluoroscopy Exam. You may drink or eat immediately following your  exam. For your results please consult your Primary Care Physician or check MyChart.
