Fig 1.

Ratios of mean values of hemodynamic and geometric variables of ruptured over unruptured mirror aneurysms. Statistically significant differences (P < .05) are indicated with an asterisk, and marginally significant differences (P < .05 on 1-sided test), with a dagger. LSA indicates percentage area under low WSS; SCI, shear concentration index; Vmax, maximum flow velocity; Q, aneurysm flow rate; ICI, inflow concentration index; norm, normal; Asize, aneurysm maximum size; Nsize, neck maximum size; AR, aspect ratio (≤ depth/neck size); VO, mean aneurysm vorticity; SR, shear rates; VE, mean aneurysm velocity.
