Circumferential wall enhancement in evolving intracranial aneurysms on magnetic resonance vessel wall imaging

Abstract

The CEAW in evolving aneurysms was higher than those in stable aneurysms, and lower than those in ruptured aneurysms. The degree of CEAW may indicate the process leading to rupture of intracranial aneurysms, which can be useful additional information to determine an indication for surgical treatment of unruptured aneurysms.
