Outline of Final Research Achievements	If cerebral aneurysm clip has no metal artifact on MRI, it is easy to check regrowth or recurrence of the aneurysm after clipping surgery. New materials of aneurysm clip were searched. However, it was difficult to find out the new materials which having mechanical endurance similar to titanium alloy.
