Sagittal antral views in the right lateral decubitus in a representative study participant. Images were taken immediately before feeding (A), then repeated every 15 min after formula feeding (B) until gastric antral cross-sectional area returned to baseline, which was at 60 min (C). Calipers labeled A and B = 2 perpendicular diameters used to calculate cross-sectional area.
