FIG 3. More detailed views of the complex aneurysm hemodynamics are provided at selected times and for selected planes via conventional field plots of sagittal (top row), coronal (middle row), and axial (bottom row) planes, each from the nominal center of the aneurysm. Contours of velocity magnitude (V, in cm/s) are shown with vectors superimposed to indicate the magnitude and direction of in-plane flow components. White circles identify the approximate center of each vortex. S, superior; I, inferior; A, anterior; P, posterior; R, right; L, left.

A, Peak systole (t = 150 ms).

B, Early diastole (t = 300 ms).

C, Mid-diastole (t = 450 ms).

D, Late diastole (t = 600 ms).
