| Outline of Final Research Achievements |
Cerebral revascularization is an established surgical treatment for intracranial aneurysm and ischemic cerebrovascular disease. However, one problem of this treatment is that we cannot predict the postoperative hemodynamics. In this study, we have integrated the measurement of blood flow in intracranial arteries by phase contrast MRI, measurement of cereral blood flow by PET/SEPCT and computationla fluid dynamics (CFD), and have clarified a part of mechanisms of local vascular adjustment and redistribution of cerebral blood flow after revascularization surgery. Results of this study will lead to the development of a simulator for cerebral blood flow in the whole brain area which predicts postoperative hemodynamics, and will contribute to the improvement of treatment results after revascularization surgery.
