  • gastric emptying scintigraphy of a radiolabeled solid meal is the gold standard for the diagnosis of gastroparesis
    • test provides a physiological, non-invasive and quantitative measure of gastric emptying
    • measurement of emptying of solids is more sensitive by scintigraphy
      • due to the fact that liquid emptying may remain normal despite advanced disease. A variety of foods including chicken, liver, eggs, egg whites, oatmeal, or pancakes are used as meals
      • content of the meal is one of the most important variables in gastric emptying
        • solids versus liquids, indigestible residue, fat content, calories and volume of the test meal, can all alter gastric emptying time
        • consensus recommendations for a standardized gastric emptying procedure have recommended a universally acceptable 99-m technetium sulfur-colloid labeled low fat, egg-white meal
