Computational Hemodynamic Analysis for the Diagnosis of Atherosclerotic Changes in Intracranial Aneurysms: A Proof-of-Concept Study Using 3 Cases Harboring Atherosclerotic and Nonatherosclerotic Aneurysms Simultaneously

Figure 10

((a)–(d)) Graphs showing the results of computational hemodynamic analysis in Case 3. (a) Pulsatile flow rates of the internal carotid artery (volume, 252.7 (mL/min); heart rate, 60 (bpm); heart beat duration (T), 1.000 (s)). (b) Volume of inflow. (c) Mean velocity inside aneurysms. (d) The spatially averaged value and the maximum value of blood age over 5 cardiac cycles. ((e) and (f)) A contour map of blood age (e) and streamlines (f) in AN8 at the time point shown in (d) (a black arrow). Note that old blood was seen around the center of the vortex indicated by streamlines (a black arrow in (f)). WSS: wall shear stress.
