Gastric emptying scintigraphy

Abstract

GES is performed to evaluate patients with symptoms associated with delayed or rapid gastric emptying. It is considered the gold standard for measuring the rate of gastric emptying. However, considerable variability in test performance has limited its usefulness due to a lack of established, standardized normal values that can be compared between institutions. To address this problem, the American Neurogastroenterology and Motility Society and the Society of Nuclear Medicine and Molecular Imaging published a consensus guideline for solid meal GES in 2008. This recommendation details precise patient preparation, meal content, acquisition method, and image processing that should be strictly adhered to by all laboratories.
