Objective To analyze the predictive value of multi-parameter MRI scan sequences for short-term stroke after transient ischemic attack(TIA).Methods A total of 80 patients with transient ischemic attack admitted to our hospital from January 2022 to December 2022 were selected for this study.All patients underwent multi-parameter MRI examination,including T1WI,T2WI,T2-FLAIR and DWI.Patients were followed up for a period of 90 days and divided into stroke group and non-stroke group according to whether they had stroke or not.The MRI risk factors related to stroke after transient ischemic attack were analyzed by univariate and multivariate analysis,and the ROC curve was drawn to analyze the relevant MRI characteristics to predict the clinical efficacy of stroke after(TIA).Results According to univariate and multivariate analysis,only intracranial artery stenosis,intracranial extracranial multi-branch artery stenosis,periventricular white matter hypersignal grade 2,deep white matter hypersignal grade 2,DWI positive,and T2 vessel hypersignal sign positive were risk factors for stroke after TIA(P＜0.05).According to ROC curve,MRI showed that intracranial extracranial multiple artery stenosis,periventricular white matter high signal level 2,deep white matter high signal level 2,and DWI positive had good predictive efficacy for stroke after TIA,with sensitivity of 50.0％,75.0％,66.7％,75.0％,respectively.Conclusion MRI parameters such as multi-branch artery stenosis,periventricular high white matter signal,deep white matter high signal grade 2 and DWI positive have good clinical efficacy in predicting short-term stroke after TIA,which can provide evidence for early clinical prevention and treatment.
