Fluoroscopy is an imaging technique commonly used to obtain real-time moving images of the internal structures of a patient through the use of a fluoroscope. The fluoroscope consists of an X-ray source and fluorescent screen between which a patient is placed.
Common procedures using fluoroscopy are investigations of the gastrointestinal track (refers to the esophagus, the stomach and the intestine), including barium meal and barium enema, hysterosalpingography and intravenous pyelography. Due to the fact that these structures do not show clearly enough for diagnostic purposes on plain radiographs, radio-opaque barium salts are used to show the shape of the lumina of these organs and therefore allow the investigation of structural and motility abnormalities. Each procedure requires special preparation before the examination.
