Lateral and oblique images show pooling of contrast in the pharynx with the aspiration of the barium contrast into the airway and inside the bronchial tree.
Evidence of oesophagal dysmotility also is seen.
The prominent aortic arc with pressure effect on the thoracic oesophagal barium column is noted.
Thoracic vertebral degenerative changes as endplate sclerosis and marginal osteophyte formation also are seen.
The fluoroscopic study is the imaging modality of choice for the investigation of dysphagia.
