| Research Abstract |
We aimed to elucidate the motion dynamics of unruptured cerebral aneurysm during the cardiac cycle by analyzing 4-dimentional CT angiography data. We were able to confirm that cerebral aneurysms show a two-peak volume change during a cardiac cycle and that the relative volume change during this cycle does not differ from that of normal cerebral arterial vessels.
