According to the 5. 0T HR-VWI results, patients were divided into an AWE group and a non-AWE group, and the differences in two-dimensional morphological parameters and clinical data between the two groups were further analyzed.  \nResults The detection rate of AWE in 5. 0T HR-VWI was higher than that in 3. 0T HR-VWI (P \u003C 0. 05) . The incidence of AWE in patients with diabetes, smoking history, aneurysm diameter ≥ 7 mm and anterior communicating aneurysms was increased (P \u003C 0. 05) . The incidence of wall enhancement in aneurysms with subcapsules and lobulated aneurysms was higher than that in aneurysms with regular morphology (P \u003C 0. 05) . The aspect ratio and size ratio of aneurysms in the group with AWE were higher than those in the group without AWE (P \u003C 0. 05) .  \n\n| †Jianxin Zhou and Qiuhong Mou contributed equally to this work and should be considered co-first authors. |\n| --- |\n| †Jiangrong Li andYun Tan made the equal contribution to this article and should be considered co-corresponding authors. |\n\n*Correspondence: Jianrong Li [1296188984@qq.com](1296188984@qq.com)[ ](1296188984@qq.com)Yun Tan [715453684@qq.com](715453684@qq.com)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2025.
