| Objective: In this study,high-resolution magnetic resonance vascular wall imaging(HR-VW-MRI)was used to investigate the correlation between the imaging features of basilar atherosclerotic plaques and the recurrence of ischemic stroke.Methods: A retrospective analysis was performed on the data of 81 patients with basilar atherosclerotic plaques who received treatment and underwent HR-VW-MRI in the Department of Neurology,the Fourth Affiliated Hospital of China Medical University from November 2018 to September 2022.Vessel Mass post-processing software was used to analyze the collected images,compare the characteristics of plaque involvement quadrant,lumen stenosis degree,lumen load,vessel remodeling mode,wall thickening mode,T1 WI with or without high signal and plaque surface condition in the relapsed group and non-relapsed group,and collect clinical data of patients at the same time.Results: A total of 81 patient images were included in the analysis,including 33 patients in the relapsed group and 48 patients in the non-relapsed group.Among the clinical features,the difference in drinking history was statistically significant,while the other clinical features were not.Among imaging features,the difference between the presence or absence of high signal on T1 WI and the surface features of plaques was statistically significant.Multivariate binary Logistic regression analysis showed that a history of alcohol consumption(P=0.011),high T1 WI signal(P=0.012)and plaque surface irregularity(P=0.019)were correlated with ischemic stroke recurrence.Conclusion: In patients with recurrent and non-recurrent ischemic stroke caused by basilar atherosclerotic plaques,there were statistically significant differences in alcohol consumption history,T1 WI with or without high signal and plaque surface condition.Patients with a history of alcohol consumption,high T1 WI signal,and irregular plaque surface have a higher risk of recurrent ischemic stroke. |
