Computer analysis of this study is accomplished by recalling the separate images and drawing regions of interest for the stomach and esophagus. The counts in the stomach region of interest and in the esophageal region of interest are noted and used to calculate a gastroesophageal reflux index for each level of abdominal pressure using the following formula: Based on GERI = (E_p/G_max) F1F1F1S1F1F1F10 100, where GERI is the gastroesophageal reflux index in percent, E_p is the esophageal counts at a specific pressure point p, and G_max is the maximum gastric count obtained for one image in this study.
