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.

颅内动脉瘤壁增强作为不稳定的指标：系统评价和荟萃分析

以前的研究已将磁共振成像上颅内动脉瘤的动脉瘤壁增强 (AWE) 描述为不稳定的替代标志物。通过这项研究，提供了针对横断面和纵向研究的 AWE 与不同特定结果（即破裂、生长或症状表现）之间关联的最新文献概述和总结风险估计。
