Visualization of Intraaneurysmal Flow Patterns with Transluminal Flow Images of 3D MR Angiograms in Conjunction with Aneurysmal Configurations

摘要

BACKGROUND AND PURPOSE: How the complex flow phenomena generated within unruptured cerebral aneurysms relate to the corresponding aneurysmal geometry is unknown. To estimate the interaction between flow patterns and morphologic features of unruptured cerebral aneurysms, we developed a method to visualize intraanuerysmal flow patterns with transluminal flow imaging of 3D MR angiograms in conjunction with aneurysmal configurations.
