This
study aimed for assessing the feasibility of in vivo trans-pyloric flow
measurements by means of phase-contrast MRI. Dynamic EPI sequences were
studied in vitro and applied in vivo behind the pylorus. The gained velocity,
frequency and backflow percentage show very good agreement with literature
values and give rise for expecting great potential in fast EPI phase-contrast
MRI for dynamic quantification of trans-pyloric mass movements.
