videofluoroskoppisesta

Videofluoroskopia, also known as videofluoroscopic swallowing study (VFSS) or modified barium swallow (MBS), is a medical imaging technique used to assess the structure and function of the swallowing mechanism. It involves using a fluoroscope, which is a type of X-ray machine that produces real-time moving images, to visualize the process of swallowing. During the examination, the patient is asked to swallow various food and liquid consistencies that have been mixed with a contrast agent, typically barium. Barium is radiopaque, meaning it shows up clearly on X-rays.

The real-time X-ray images are recorded as video, allowing clinicians to observe the movement of the food or liquid through the oral cavity, pharynx, and esophagus. This visualization helps identify any abnormalities or difficulties in the different stages of swallowing, including oral preparation, oral transit, pharyngeal transit, and esophageal transit. It can reveal issues such as aspiration (food or liquid entering the airway), penetration, residue in the pharynx, or delayed swallow initiation.

Videofluoroskopia is a diagnostic tool commonly used by speech-language pathologists, radiologists, and gastroenterologists. It is particularly valuable in evaluating patients with suspected dysphagia (swallowing difficulties) resulting from neurological conditions like stroke, Parkinson's disease, or head and neck cancer, as well as structural abnormalities or post-surgical changes. The information obtained from a VFSS guides treatment decisions, such as dietary modifications, swallowing therapy strategies, or recommendations for alternative nutrition and hydration.
