Figure 3
Examples of (a) anterior and (b) posterior geometries (not to scale) from the same subject and cuts from which the computed pressure was read. In the bottom row are general schematic illustrations of the (c) anterior and (d) posterior boundary conditions used for the CFD. The flow rates were assessed by 4D flow MRI. Note the variability in sign for \({Q}_{PCoA}\), introduced as an additional inlet requires a reduction of the corresponding \({Q}_{ICA}\) in anterior models and \({Q}_{BA}\) in posterior models to preserve mass conservation.
