Screening in Relatives With Elevated Risk for Unruptured Intracranial Aneurysms

The purpose of this study is to screen first-degree relatives of patients with aneurysmal subarachnoid hemorrhage using magnetic resonance angiography to detect unruptured intracranial aneurysms. This study aims to identify individuals who are at increased risk and determine the effect of environmental factors for development of unruptured intracranial aneurysms.
