Barium swallow, also called an oesophagogram, involves making the patient swallow barium contrast while the oesophagus is imaged by fluoroscopy. This allows visualisation of food moving through the oesophagus in real time. | Barium swallow, also called an oesophagogram, involves making the patient swallow barium contrast while the oesophagus is imaged by [[fluoroscopy]]. This allows visualisation of food moving through the oesophagus in real time. A "filling defect" on the barium swallow, defined as a portion of the oesophagus which isn't filled by the barium contrast, can be due to: | ||
