MRI for the evaluation of gastric physiology

Abstract

Background:: Evaluation of gastric physiology (gastric emptying and motility) is important for the diagnosis of disturbances such as functional dyspepsia. MRI is a non-invasive technique that allows simultaneous registration of gastric emptying and motility. Aim:: To provide an overview of the literature of studies that used MRI as a tool for evaluation of gastric function in both research and clinical settings. Materials and methods:: A MEDLINE search was performed (1990-2008) directed at the radiology and gastroenterology literature on gastric physiology. Key words that were used included: functional tests, gastric emptying, gastric motility, gastric physiology and MRI. Twenty-five articles fulfilled the inclusion criteria and were included in the analysis. Results and conclusion:: Over the last decade, MRI has developed as a reliable, non-invasive method for detailed evaluation of gastric emptying and motility without the disadvantages of ionizing radiation and without the use of intragastric catheters that influence gastric physiology. © 2010 The Author(s).
