Thoracic Esophageal and Pharyngeal Barium Swallow Fluoroscopy
This real-time X-ray fluoroscopy procedure requires patients to swallow a barium sulfate contrast agent to capture dynamic, moving images of the pharynx and thoracic esophagus, the exact anatomical regions targeted in this exam. It is clinically indicated for evaluation of upper gastrointestinal conditions including dysphagia, esophageal strictures, achalasia and other motility disorders, Zenker’s diverticulum, and structural damage from chronic reflux or injury, as it can detect functional movement abnormalities that static X-ray or CT imaging cannot identify. The minimal radiation dose used during the 10-minute procedure ensures low patient exposure while providing high-resolution real-time visualization of the barium as it travels through the upper gastrointestinal tract.
This fluoroscopic barium swallow uses real-time X-ray imaging to assess the dynamic function and anatomical structure of the pharynx and thoracic esophagus for diagnosis of upper gastrointestinal swallowing disorders and structural pathologies.
