@article { , title = {Spatio-Temporal Motility MRI (STMM) analysis of the stomach and colon}, abstract = {Background: MRI is increasingly used to objectively assess gastrointestinal motility. However, motility metrics often do no not offer insights into the nature of contractile action. This study introduces a systematic method of making spatiotemporal measurements of contractions, based on changes in bowel lumen diameter. Methods: Two heterogeneous cohorts of subjects were selected displaying gastric (n = 15) and colonic motility (n = 20) on which to test the Spatio-Temporal Motility MRI (STMM) technique. STMM involved delineating the bowel lumen along with inner and outer bowel wall along a section of the gastrointestinal tract. A series of diameter measurements were made automatically across the central axis of the lumen. Measurements were automatically propagated through the time series using a previously validated algorithm. Contractions were quantitatively summarised with two methods measuring 1) Normalised Contraction Plot (NCP) and 2) Combined Velocity Distance (CVD) both of which can be visualised as spatiotemporal motility maps. Both metrics were correlated against subjective visual scoring systems. Key Results: Good correlation was seen between reader scores and both motility metrics (NCP, R = 0.85, P}, doi = {10.1111/nmo.13557}, eissn = {1365-2982}, issue = {5}, journal = {Neurogastroenterology and Motility}, note = {Article not yet in issue.
