Fluoroscopy
An X-ray exam that allows radiologists to use a real time imaging techniques. Unlike traditional X-ray, which produces still pictures, fluoroscopy can capture full motion.  It is often used to examine the entire gastrointestinal tract, specifically to pinpoint blockages or other abnormalities.

Fluoroscopy is a type of X-ray exam that allows radiologists to use "real-time" imaging techniques. Unlike traditional X-ray, which produces still pictures, fluoroscopy can capture full motion. For example, the esophagus can be visualized during swallowing under fluoroscopy. Common fluoroscopic tests include Upper GI and Barrium Enema.

This technique is often used to examine the entire gastrointestinal tract, specifically to pinpoint blockages or other abnormalities. Contrast agents such as barium and air can be used to increase visibility by lining the organs. The contrast is usually swallowed or introduced with an enema.

Preparing for this test: Fluoroscopic exams which generally take between 30 minutes to an hour -- require a certain amount of preparation. You will most likely be asked not to eat or drink anything between midnight and the appointment time. Tests involving a barium enema may require you to avoid solid foods for a day prior to the exam. A diet of clear liquids is usually required for at least 12-48 hours. A mild laxative may also be needed to clear the colon before the procedure.
