The high speed echo-planar NMR imaging technique is particularly suitable for visualizing human gut motility and transit. To enable a quantitative study of the rheology of the stomach contents, the magnetization can be prepared using a SPAMM (SPAtial Modulation of Magnetization) tagging sequence prior to imaging. Movement of stomach contents has been measured and analyzed temporally and in the Fourier domain and correlated with stomach motility. Increased stomach activity combined with retropulsive motion were observed at about 25 min following a porridge meal, indicating mixing of the meal and inhibition of gastric emptying.
