What is a single contrast Esophagram?
Routine single-contrast esophagography includes fluoroscopic observation of the esophagus supplemented by motion recordings, full-column views, and mucosal relief views. Full-column (barium-filled views) and mucosal relief views constitute the single-contrast phase of the examination.
What is the difference between single and double contrast barium?
Single contrast barium enema is not suitable in these situations because it is less sensitive at detecting small polyps and early changes of inflammatory bowel disease. The ‘double contrast’ refers to the use of positive and negative contrast agents to increase the sensitivity of the examination.

What is a double contrast barium swallow for esophageal cancer?
double contrast barium swallow is the preferred mode of examination. the patient swallows a packet of effervescent agent and then rapidly gulps a packet of high-density barium. frontal and left posterior oblique views are taken. two exposures are centered on the upper/mid esophagus and two on distal esophagus.
