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

Contour maps of RRT ((a) and (d)), time-averaged WSS ((b) and (e)), and OSI ((c) and (f)) in Case 1. The aneurysm with atherosclerotic changes (AN2) presented with long RRT and low WSS. Black arrows indicated the point with the longest RRT (117.3 (1/Pa)), the lowest WSS (0.02 (Pa)), and the highest OSI (0.36) in AN2. See also Table 2. RRT: relative residence time, WSS: wall shear stress, and OSI: oscillatory shear index.
