Videofluoroskoopiline
Videofluoroscopic examination, often referred to as videofluoroscopy or VFSS, is a medical imaging technique that uses a continuous X-ray beam to create real-time moving images of internal body structures. It is particularly valuable for assessing dynamic processes, such as swallowing and speech production. During a videofluoroscopic study, a patient is typically given a contrast agent, such as barium, which is visible on X-ray. This allows clinicians to visualize the passage of food or liquid through the pharynx and esophagus, identifying any abnormalities in the swallowing mechanism. The real-time nature of videofluoroscopy enables detailed observation of the coordinated muscle movements involved in these functions. The images are recorded and can be reviewed and analyzed frame by frame. This diagnostic tool is commonly employed by speech-language pathologists and radiologists to evaluate and manage swallowing disorders, also known as dysphagia, and to investigate potential causes of aspiration, where food or liquid enters the airway. The procedure is generally safe, with radiation exposure minimized by using the lowest effective dose.
