Description

The cerebral arteries in rats are reconstructed and the blood flow dynamics are performed by micro-CT for investigating cerebral aneurysms such as mechanism of generation, growing, and rupture of aneurysm. The cerebral arteries in rats were extracted from the brain by using cast techniques. The 3-D reconstruction of arteries by micro-CT indicates the possibilities of computational flow dynamics (CFD). The contrast media was injected from the external carotid artery into the cerebral arteries. The blood flow flushing the contrast media in cerebral arteries observed by micro-CT may allow the trace of blood flow using the cinematic angiography method, if the time resolution increases.
