FIG 5. Two sequential frames from 2-Hz cine digital subtraction angiograms. These zoomed views correspond to the orientation and extent of the CFD model in the lower panels of Figure 2C and D.

A, Aneurysm filling dynamics, shown approximately 0.5 second after selective injection into the internal carotid artery, show good general agreement with the corresponding virtual slipstreams shown in Figure 2C.

B, One frame (ie, 0.5 second) later, the aneurysm is already largely opacified, which also is consistent with the corresponding virtual slipstreams shown in Figure 2D.
