Intracranial aneurysm wall enhancement as an indicator of instability: a systematic review and meta‐analysis

Background and purpose Aneurysm wall enhancement (AWE) of intracranial aneurysms on magnetic resonance imaging has been described in previous studies as a surrogate marker of instability. With this study, an updated literature overview and summary risk estimates of the association between AWE and different specific outcomes (i.e., rupture, growth or symptomatic presentation) for both cross‐sectional and longitudinal studies are provided.
