Fluoroscopy is an imaging technique that uses X-rays to obtain real-time moving images of the interior of an object.
Fluoroscopy uses x-rays to create images of the internal organs in real time. Computers help create images of the structures while oral contrast is used to enhance these images. Fluoroscopy is used to help diagnosis problems with your esophagus, stomach, duodenum and small bowels. This procedure allows doctors to visualize the movement of oral contrast through the digestive system in real time. If you are scheduled for a fluoroscopy, don't eat or drink anything, other than water, after midnight.
You should have had no other contrast studies within 24-48 hours of your exam. Bring a list of your current medicines. You may take your regular medications with small amounts of water. Drink plenty of water the day before and after the exam. Tell the nurse or technologist if you are allergic to any medicine or have received a high-density contrast procedure (example: barium swallow or CT scan).
