The Association of Aneurysm Wall Enhancement with Hemodynamic Relationships Between the Aneurysm Neck and Parent Artery

Motivation: To investigate the relationship between the enhancement of intracranial cystic aneurysm walls and aneurysm morphology and hemodynamics. Goal(s): The study aimed to identify new imaging indicators for intracranial aneurysm enhancement. Approach: We conducted a retrospective collection of magnetic resonance images of aneurysm cases and grouped them based on aneurysm wall enhancement grades. Then the differences in morphological and hemodynamic parameters between groups were compared. Results: The study found that the maximum flow rate at the aneurysm neck and the ratio of the aneurysm neck to the maximum flow rate of the parent artery were statistically significant. Impact: This study investigated the hemodynamic relationship between aneurysms and the parent artery, and its potential impact on aneurysm wall enhancement. These results could offer valuable insights into the connection between aneurysm wall enhancement and hemodynamics.
