2D cine PC MRI measured increased temporally averaged flow velocity after the meal challenge only in the proximal and distal section, not in the curved mid section. The average velocities were highest and their standard errors were smallest at the distal straight section both before and after the meal challenge as compared to other sections irrespective of cardiac phase.
