Figure 3.

Time-averaged velocity magnitude acquired with 4D flow MRI (top) and calculated with CFD (middle) and corresponding black-blood MR images (bottom, after administering contrast agent, with 0.7 mm3 isotropic voxel size) for model 1 supplied with 160 and 266 ml/min average flow rate. Note that the 4D flow MRI and CFD revealed similar flow patterns: a strong forward flow (yellow arrowheads), reverse flow along the aneurysm wall (white arrows), and stagnation region of low velocity in the center of the aneurysm sac (dashed circles). Areas of high velocity were colocalized with low-signal areas (dashed squares).
