Question

Having the patient drink during the exposure will ensure that more contrast media fills the esophagus, resulting in better visualization. The Valsalva maneuver and Müller maneuver may cause changes in intra-thoracic pressure, but they will not improve filling of the esophagus. Shortening the exposure time will not improve filling, but may result in an underexposed image.
