Note:—BIF indicates bifurcation; CORELEN, vortex core length - flow complexity; ICI, inflow concentration index; LAT, lateral; LSA, low shear area (% of aneurysm sac); MWSSnorm, maximum normalized WSS; OSImax, maximum oscillatory shear index; OSImean, mean oscillatory shear index; PODENT, proper orthogonal decomposition entropy—flow stability; Q, aneurysm inflow rate; SCI, shear concentration index; SR, mean aneurysm shear rate; VE, mean aneurysm velocity; Vmax, maximum aneurysm velocity VO, mean aneurysm vorticity; WSSmax, maximum WSS; WSSmean, average WSS; WSSmin, minimum WSS; WSSnorm, normalized WSS.
↵a R indicates mean value significantly larger (P < 0.05) in ruptured compared with unruptured aneurysms. U indicates mean value significantly larger (P < 0.05) in unruptured compared with ruptured aneurysms. B indicates mean value significantly larger (P < 0.05) in BIF compared with LAT aneurysms. L indicates mean value significantly larger (P < 0.05) in LAT compared with BIF aneurysms. Empty cells indicate no statistically significant difference.
