videofluoroskopische

Videofluoroscopy, sometimes rendered as videofluoroscopic imaging, is a radiographic technique that captures real-time motion of internal structures under X-ray fluoroscopy. In clinical contexts, the adjective videofluoroskopische is used in German-speaking literature to refer to studies that image dynamic processes, such as swallowing, with simultaneous X-ray video recording.

During a typical procedure, the patient ingests contrast material (commonly barium) of varying consistencies while a fluoroscopic X-ray system records dynamic sequences. The continuous or high-frame-rate video allows clinicians to assess bolus transit, airway protection, and esophageal motility. The test is usually interpreted by a radiologist with input from a speech-language pathologist or gastroenterologist.

Applications include evaluation of dysphagia, esophageal motility disorders, gastroesophageal reflux, and postoperative dysfunction. It provides functional information beyond static imaging, guiding therapy, dietary modifications, and treatment planning.

Radiation exposure is a consideration; dose optimization and adherence to ALARA principles are standard. Limitations include reliance on patient cooperation, variability in technique, and the need for specialized equipment and expertise. It is not a substitute for structural imaging when needed.

Since its development in the late 20th century, videofluoroscopy has become a routine, widely used method in both radiology and speech-language pathology for functional assessment of the upper aerodigestive tract.
