A Fluoroscopy is an examination of the upper or lower GI and is performed by a radiologist. For both the upper and lower GI exam, a technologist will gently position you on a special tilting table supporting a piece of equipment called a Fluoroscope (an x-ray machine combined with a television screen). Digital spots will be taken of the areas your doctor wishes to study.
In order for the radiologist to help diagnose your medical issue, you will be asked to properly prepare for the exam. For the upper GI you will be asked to drink a liquid barium mixture(s). For the lower GI you will have rectal barium contrast through an enema. The oral contrast highlights the esophagus, stomach and small bowel, while the rectal contrast highlights the colon or large bowel. These particular examinations are looking for ulcers, polyps, and other abnormalities of the bowel.
How do I prepare for a Fluoroscopy?
Depending on which part of your body is being scanned, you may be asked to:
- Refrain from eating or drinking from midnight the day before your exam until the exam is completed
- You may be asked to change into a patient gown. A gown will be provided for you. Lockers are provided to secure your personal belongings. Please remove all piercings and leave all jewelry and valuables at home
- Patients having a barium enema will have a specific bowel preparation the evening prior to the requested examination
If you know you are allergic to iodine contrast or are diabetic or hypertensive, please advise your physician and the technologist before your examination.
As with all radiological procedures, please inform the technologist if there is any chance you are pregnant.
