Inter- and Intrasubject Variability of Total Gastric Volumes in Response to Isocaloric Liquid Meals in Functional Dyspepsia and Health

Aims: Measurement of gastric emptying by scintigraphy, ultrasound or breath test has a considerable interindividual variability. However, data on the reproducibility of non-invasive total gastric volume measurements are sparse. Aims: To compare gastric volume responses to ingestion of isocaloric liquid meals and document the inter- and intraindividual reproducibility of gastric volume measurement using a validated MRI technique in patients with functional dyspepsia (FD) and healthy controls (HC). Methods: 8 healthy controls and 8 dyspeptic patients underwent a MRI study on two different occasions after an eight…
