Objectives: The aim of this study was to determine the shape and area of the pharyngoesophageal segment (PES) during swallowing using 320-row area detector computed tomography, which can acquire a volume data set covering a 16-cm area in a single rotation. Methods: Twenty healthy subjects were scanned during swallowing 3, 10, and 20 mL of honey-thick barium (5% w/v). PES was identified using cross-sectional images of 0.5-mm slice thickness, and the area in each section was measured. Results: The PES opening area and the anteroposterior and lateral diameters of the PES were volume dependent. However, there was no statistical difference in anteroposterior and lateral diameters between 3- and 10-mL bolus swallowing. Conclusions: Three hundred twenty–row area detector computed tomography provided new information about PES. This technique will facilitate further understanding of the mechanisms of PES opening and swallowing physiology.
