Total gastric (TGV) and meal volumes (MV) were assessed every five minutes for 90 minutes, in and interspersed with dynamic scan sequences (duration: 2.78 minutes) providing detailed images of distal ACWs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>TGV increased by 738 \u00b1 38 mL after ingestion (t<jats:sub>0<\/jats:sub>), subsequently decreasing in parallel to GE. The mean GE rate and half\u2010emptying time were 24 \u00b1 3 mL\/5 minutes and 71 \u00b1 6 minutes, respectively. Accompanying ACWs reached a periodicity of 23 \u00b1 2 seconds at t<jats:sub>35<\/jats:sub> and propagated at an unvarying speed of 0.27 \u00b1 0.01 cm\/second. Their amplitude of 0.70 \u00b1 0.08 cm was constant, but the width decreased along the antral wall by 6 \u00b1 2%\/cm (<jats:italic>P<\/jats:italic> = 0.003). ACWs were nonocclusive (percentage occlusion 58.1 \u00b1 5.9%, t<jats:sub>0<\/jats:sub> at the pylorus) with a reduction in occlusion away from the pylorus (<jats:italic>P<\/jats:italic> &lt; 0.001).
