Aneurysm wall enhancement (AWE) as seen on high-resolution vessel wall imaging (VWI) sequences has been an interesting yet controversial topic within recent years. Some studies have proposed that the presence of AWE may be a harbinger to aneurysm instability and rupture, whereas the lack of enhancement may indicate a lower likelihood of impending rupture. If these relationships were to be true, VWI of unruptured intracranial aneurysms would likely be a useful tool in risk stratification and deciding whether or not an aneurysm requires intervention. This is particularly true in cases of clinical equipoise where the decision to treat does not surely meet criteria for intervention vs observation. Furthermore, VWI could be useful in monitoring changes in unruptured aneurysms that are followed over time....

评论：动脉瘤壁增强与囊内 IL-10 降低和不稳定性的形态学特征相关

近年来，在高分辨率血管壁成像 (VWI) 序列上看到的动脉瘤壁增强 (AWE) 一直是一个有趣但有争议的话题。一些研究提出，AWE 的存在可能是动脉瘤不稳定和破裂的先兆，而缺乏增强可能表明即将破裂的可能性较低。如果这些关系成立，未破裂颅内动脉瘤的 VWI 可能是风险分层和决定动脉瘤是否需要干预的有用工具。在临床平衡的情况下尤其如此，在这种情况下，治疗决定不一定符合干预与观察的标准。此外，VWI 可用于监测随时间推移的未破裂动脉瘤的变化......
