Abstract：Objective To investigate the value of vessel wall magnetic resonance imaging(VWI-MRI)in the stabili-ty of unruptured intracranial aneurysms(UIA).Methods A total of 120 patients with UIA admitted to our hospital from Jan-uary 2021 to January 2023 were selected and divided into stable group(n=64)and unstable group(n=56)according to the stability of aneurysms.VWI-MRI examinations were performed,and VWI-MRI parameters were compared between the two groups and patients with different growth and rupture risk within 5 years[location,forked aneurysm,shape,form of enhance-ment,wall enhancement grade,enhancement index,tumor depth,neck width and tumor width].The correlation between VWI-MRI parameters and the stability,growth and rupture risk of UIA within 5 years was analyzed.Results There were sig-nificant differences between stable group and unstable group and between low-risk and high-risk patients with respect to bifur-cation aneurysm,morphology,type of reinforcement,grade of wall reinforcement and WEI(P＜0.05,P＜0.01).The stabil-ity,growth within 5 years and rupture risk of UIA were positively correlated with bifurcation aneurysms,morphology,type of reinforcement,grade of wall reinforcement and WEI(P＜0.01).Conclusion VWI-MRI can be used to evaluate the stabili-ty of UIA,and provide reference for early clinical assessment of aneurysm growth and rupture risk.
