Videofluoroskgópos

Videofluoroscopy is a medical imaging technique that uses a continuous X-ray beam and a video recording system to visualize internal bodily structures in motion. It is particularly useful for evaluating dynamic processes. The procedure involves the patient ingesting or being exposed to a contrast agent, typically barium or iodine-based, which coats or fills the area being examined. The X-ray beam passes through the body, and the contrast material blocks the X-rays, making the structures visible on a fluoroscopic screen. A video camera captures these images in real-time, allowing for playback and detailed analysis.

This diagnostic tool is widely employed in various medical specialties. In gastroenterology, it is used to assess swallowing function (videofluoroscopic swallowing study or VFSS), evaluate the esophagus, stomach, and intestines, and diagnose conditions like reflux or motility disorders. In urology, videofluoroscopy can help visualize the urinary tract during micturition or barium enemas for colon imaging. Orthopedics may use it to examine joint movement or the placement of orthopedic devices. The real-time nature of videofluoroscopy allows clinicians to observe functional abnormalities that might not be apparent on static X-rays. The radiation dose is a consideration, and the procedure is performed with the lowest effective dose necessary.
