Brief Summary:
10-20 of patients with subarachnoid hemorrhage die before they arrive at the hospital and about 25 die within 24 hours About 1 of patients are diagnosed with cerebral aneurysms in imaging tests for health checkups and many of them experience aneurysmal rupture during their lifetime so it is not a rare disease Wall shear stress is known to be a factor that reflects the state of blood vessels and particularly plays an important role in the patency of the intima of blood vessels In the meantime computed fluid dynamics CFD a representative method for calculating wall shear stress assumes a virtual rigid pipe and applies a preset value This does not accurately reflect the physiological and dynamic state of the actual blood vessel The investigators intend to measure the patients wall shear stress using the SIG of the MRA-TOF technique which reflects the physiological characteristics of individual patients and to analyze the association with rupture of the intracranial aneurysm
