This study aimed to demonstrate the feasibility of aneurysmal wall enhancement (AWE) and wall enhancement index (WEI) in the identification of symptomatic and asymptomatic unruptured intracranial aneurysms by using vascular wall magnetic resonance imaging (VW-MRI) in a large cohort of Chinese patients with unruptured intracranial aneurysms (UIAs). VW-MRI were obtained at MAGNETOM Skyra/Verio/Prisma 3T MR scanner (Siemens Healthcare, Erlangen, Germany) in these patients. We found CAWE and WEI>0.91 were more frequently identified in symptomatic UIAs.
