X-ray are used concomitantly with contrast media in a procedure known as barium swallow. It is useful when visualizing strictures and masses in the esophagus. The most prominent findings in barium swallow with esophageal cancer include, shouldering and tapering strictures.
A barium contrast esophagram or barium swallow is performed as the initial test (prior to upper endoscopy) in patients with esophageal cancer.[1][2][3]
The patient swallows barium rapidly and the esophagus is imaged using x-rays.
A confirmatory finding of esophageal cancer with barium swallow includes:
