Velocity fields measured with phase contrast (PC) MRI
generally do not satisfy the equations of fluid
dynamics. A framework for using MRI measurements to
construct a flow field that satisfies such equation was
previously described. However, only one MRI-measured
velocity component was used to drive the computational
fluid dynamics (CFD) solution. We investigate the use of
3D PC-MRI to guide the CFD calculations. The results
show that MRI-guided CFD is effective in correcting the
MRI-measured velocity field, and suggest that using 3D
PC-MRI to guide the CFD solution produces results that
are more truthful to the MRI measurements.
