Fluoroscopy

Fluoroscopy is real-time X-ray imaging that shows organ movement, such as swallowing or contrast flowing through the digestive tract. It is often used for procedures that need visual guidance.

How it works

Unlike a standard X-ray that produces a single image, fluoroscopy produces a continuous sequence. Doctors can see organ motion, such as the esophagus, stomach, and bowel, as the patient moves or swallows.

Contrast is often used to highlight the structures of interest. Barium or water-soluble contrast is chosen according to need.

Common uses

Fluoroscopy is used for swallowing studies (videofluoroscopy) when there is difficulty swallowing, upper and lower gastrointestinal studies, and procedures such as stent or catheter placement that require image guidance.

In some procedures, fluoroscopy helps confirm the correct position of a device without opening the body.

Radiation safety

Because the exam lasts longer than a standard X-ray, radiation dose can be higher. Medical teams therefore keep exposure time as short as possible.

Patients and staff are protected with lead shielding and controlled distance. Pregnant patients should inform their doctor before the exam.

Key points

• Used for digestive tract studies and certain procedures.
• Doctors aim to keep radiation exposure as low as possible.
