Overview
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.
Barium swallow
- 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:
- Tapering stricture known as a "rat's tail"
- Irregular stricture
- Pre-stricture dilatation
- Shouldering
