Table 2. Morphological and hemodynamic parameters.
Group’s median values for ostium area, parent vessel area (proximal to the aneurysm), aneurysm volume, and non-sphericity index are calculated, as well as the corresponding standard deviations. In addition, cycle-averaged aneurysm neck inflow rate, parent vessel flow rate (proximal to the aneurysm), spatial mean aneurysmal velocity, and spatial mean WSS are listed.
