Fluoroscopy is a medical imaging technique that uses X-rays to produce real-time moving images on a monitor. It allows doctors to observe how internal structures move and can also show the movement of contrast material, catheters, instruments, or devices inside the body. FDA describes it as being similar to an X-ray movie.

Fluoroscopy is used for many different examinations and procedures. Common examples include barium swallow, Upper GI studies, selected Lower GI contrast studies, urinary studies, swallowing assessments, catheter guidance and selected orthopedic procedures. The exact examinations offered at AS Medical Complex depend on available equipment and specialist services.

Yes. Fluoroscopy uses ionizing X-ray radiation. Radiation exposure varies according to the examination and how long fluoroscopy is required. Complex interventional procedures may involve greater exposure than short diagnostic studies. FDA recommends using the lowest acceptable radiation exposure for the shortest necessary time.

It depends on the examination. Upper GI studies commonly require an empty stomach, while Lower GI examinations may require bowel preparation. Other fluoroscopic procedures have completely different preparation requirements. Patients should follow the specific instructions provided for their scheduled examination.

Fluoroscopy uses ionizing radiation, so patients should always tell their doctor and Radiology team if they are or may be pregnant. Whether an examination proceeds depends on the clinical need, body area, pregnancy stage, radiation exposure and whether ultrasound or MRI can provide the required information without ionizing radiation.

A standard Barium Swallow or esophagram mainly evaluates the esophagus and movement of swallowed contrast toward the stomach. A Modified Barium Swallow or Videofluoroscopic Swallow Study focuses more closely on the swallowing process in the mouth and throat, including whether food or liquid enters the airway. A Speech and Language Pathologist often participates in the modified study.

No single examination is better for every problem. Fluoroscopy is particularly useful for observing movement, function, contrast passage and procedure guidance. CT provides detailed cross-sectional imaging and is particularly important for many emergencies. MRI provides excellent soft-tissue imaging without ionizing radiation. Endoscopy allows direct visualization of the gastrointestinal lining and can permit biopsy or treatment. The appropriate investigation depends on the clinical question.
