May improve CFD accuracy in research models; animal data leaves open human validation before clinical use.
For computational fluid dynamics calculations based on MRI velocity measurements, using MRI-measured velocities as fixed inflow boundary conditions—after filtering and scaling—provides the most accurate flow profiles.
Glor et al. (2002) studied this question. MRI velocity measurements as fixed velocities vs. Other inflow boundary condition types was evaluated on Accuracy of the velocity profile in CFD simulation. Using MRI-measured velocities at the inflow plane as fixed velocities, corrected for partial volume effect and scaled to the correct flow rate, optimizes CFD inflow boundary conditions.
