Figure 1 This schema illustrates the procedure of esophageal infusion and brain positron emission tomography scanning. The infusions were performed twice for pH 1 and 7 solutions (distilled water) and once for the pH 2 solution. In order to counterbalance the effects of the infusion order, the order was randomly selected per each subject from pH 1-7-2-7-1, pH 7-1-1-7-2 and pH 2-1-7-7-1 as shown. 1First infusion; 2Second infusion; PET: Positron emission tomography.
