Abbreviations for aneurysm location: ACOM anterior communicating artery, ACA anterior cerebral artery, AChA anterior choroidal artery, ICA internal carotid artery, MCA middle cerebral artery, PcomA posterior communicating artery. Mean aneurysm diameter in the axial plane. Time needed for 2D manual and 3D computer aided segmentation. Pulsation Group: 1 –with a pulsation like volume profile similar to the arterial pulse wave, 2 –with a randomly oscillating volume profile, 3 –with a predominantly flat volume profile.
