Abstract

In order to define a suitable volume of barium to be delivered to patients during the radiographic evaluation of pharyngoesophageal function during swallowing, three different age groups of nondysphagic volunteers were studied. Subjects randomly swallowed boluses of water, barium, and Coca-Cola. The size of a normal thin liquid bolus was 21 ml (SD±5 ml). We intend to include this information to compare different bolus sizes in cineradiographic examination of patients with swallowing complaints.
