Fluoroscopy is a radiological technique where a low dose of x-rays are combined with an image intensifier to create an image on a monitor which allows real time evaluation of several parts of the body. The most common exams are barium swallow, upper GI, small bowel follow through, lower GI (barium enema), and procedures such as myelogram, arthrogram, and lumbar puncture.  Fluoroscopy almost always requires the use of a contrast agent that is either ingested or injected.  With the assistance of a radiologic technologist, a radiologist or a physician extender will perform the examination, taking several films for review and documentation, and send a report to your physician.  Fluoroscopy is commonly used to diagnose swallowing difficulties and gastrointestinal abnormalities, evaluate joint capsules and spinal cord pathology, or to administer medications.
