Measurement by 4D flow MRI along the falcine sinus. (A) The flow rate at different sites (6.9 mm and 19.5 mm) along the falcine sinus (pathologic flow) of VOGM2 has been measured by 4D flow MRI, as shown by the blue and orange annotations on axial 2D TOF MRA. (B) The inflow rates at these two locations are plotted over a sampled cardiac cycle. The average inflow of the two locations has been used as the inflow boundary condition in CFD simulations.
