WebAdditionally, there are differences between hospitals about how the quantitative data is reported. Hospitals may measure any of the following: Time to half-empty gastric contents; Rate of gastric emptying (percentage per minute) Percent of gastric emptying at different time intervals (e.g. 30 minutes, 1 hour) WebMethods: All gastric emptying scans performed at our institution over a 3.5-yr period were studied. Raw data from these studies were analyzed by nonlinear curve fitting. Using the equation: If (x < xo, plateau, plateau * exp ( - K * (x - xo))) data were best fit to a function describing a lag followed by a log linear decay.
