videofluoroszkópos

Video fluoroscopy, known in Polish as videofluoroszkop or videofluoroszkópos, is a medical imaging technique that records X‑ray images in real time to produce continuous video of moving internal structures. The method is widely used to evaluate swallowing function (dysphagia), gastrointestinal motility, and the dynamic behavior of bones and joints. During a study the patient swallows a radiopaque contrast agent while a fluoroscopic unit captures moving images at a frame rate of 15–30 frames per second. A high‑speed digital flat‑panel detector and advanced image processing software produce a clear, real‑time feed that can be recorded and reviewed in detail.

The advantages of videofluoroskgópos include its ability to show functional movement, relative non‑invasiveness, and efficiency compared with static radiography. It can reveal transient abnormalities such as bolus stasis, cricopharyngeal dysfunction, or intermittent strictures that would be missed on a single static image. However, the technique does expose the patient and staff to ionizing radiation; therefore, radiation dose is minimized by collimation, using the lowest effective exposure, and following the ALARA principle. Contrast media are required, which can pose a risk of allergic reaction or, very rarely, aspiration. The procedure is limited to two‑dimensional visualization and cannot provide volumetric data, so complementary imaging such as MRI or endoscopy may be necessary for full anatomical assessment.

Equipment for videofluoroskgópos consists of an X‑ray source, a flat‑panel detector, a display monitor, and a console that allows the operator to adjust exposure, frame rate and video playback. Recent advances in detector sensitivity and digital image storage have improved image resolution while reducing radiation dose. Videofluoroskgópos is used not only in clinical diagnostics of swallowing and gastrointestinal disorders but also in sports medicine for analyzing joint kinematics under load, making it a versatile tool in both routine and specialized medical imaging.
