This study presents bowel motility assessment with Continuously Tagged MR imaging. This technique employs conventional MR-tagging, modified for non-periodic motion, from which spectral information was extracted when the tag pattern was deformed by tissue motion. Spectral analysis for different frequencies was performed. This non-invasive, free breathing and automated technique detected changes in bowel motility in a group of ten healthy volunteers after administration of a spasmolytic agent. Both in lower and higher frequencies significant decrease in motility was observed.
