Fluoroscopy

Fluoroscopy is a type of x-ray exam that allows radiologists to use real-time (TV like) motion analysis with x-rays. Unlike traditional x-rays, which provide still pictures, fluoroscopy captures full motion.

Fluoroscopy is often used to examine the entire gastrointestinal tract, particularly to pinpoint blockages or other abnormalities. Contrast agents such as barium sulfate, iodine compounds and air can be used to increase visibility by lining the organs so that they absorb x-rays. The contrast agents are generally introduced by enema or swallowed. Some types of fluoroscopy procedures you may have heard of are lower GI, upper GI and barium swallow.

Getting Ready For a Fluoroscopic Exam:
Fluoroscopic exams require a certain amount of preparation. You will probably be asked to fast between midnight and your appointment time. We will inform you of any type of preparation at the time your exam is scheduled. If you have questions about what you need to do, please give our office a call.

Tests involving a barium enema may require you to avoid solid foods for a day or two prior to the exam. A clear liquid diet is usually required for at least 12 to 24 hours prior to the exam and a mild laxative may also be needed to clear the colon before the procedure.

The Test:
During a Fluoroscopic exam your body may be repositioned several times to capture views from a variety of angles. The insertion of a tube in the rectum in order to deliver barium or air may be slightly painful. Your RDI technologist will do everything possible to make your procedure as comfortable as possible. The entire procedure will probably take between 10 minutes to an hour.

After the Test:
After the examination, you may be given a laxative or enema to wash the barium out of your system. In some instances, the radiologist may require additional images after the contrast is cleared , as well as while full of barium. We encourage you to drink additional water for 24 hours after the examination to help clear your system of the contrast. Usually a few hours of rest at home will enable you to completely resume your daily activities.

Some patients experience mild itching for a time after the exam as a result of an allergy to either barium or the latex tubes used during barium enemas. Other rare reactions may include shortness of breath, swelling of the throat or hives. Consult your physician if you experience any side effects that do not clear up within a few hours.

Usually a few hours of rest at home will enable you to completely resume your daily routine.
