=== Oesophageal manometry ===
Manometry is the gold standard for diagnosis of motility disorders. It uses a transnasal catheter with pressure sensors to analyse pressure at different points in the oesophagus, allowing analysis of the peristaltic waves in the oesophagus.

=== Barium swallow ===
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:

A double-contrast oesophagogram refers to when barium is swallowed first, then air or CO2 releasing tablets.
