The Clinical Application of SWI in Cerebral Microbleeds Correlated with Acute Ischemic Stroke

Objective To assess the imaging features of Cerebral microbleeds(CMBs)in ischemic stroke patients using susceptibility weighted imaging(SWI).Materials and Methods A total of one hundred ischemic strock patients were enrolled in this study.The imaging protocol involved T2-weighted imaging,T1-weighted imaging,diffusion-weighted imaging(DWI),SWI.The correlation between vascular risk factors and radiological findings including CMBs location and white matter hyperintensity was analysed.Results CMBs were found on SWI in 17 patients(17%).The most common location of CMBs was the basal ganglia,followed by the corticosubcortical region,the thalami,the brainstem,and the cerebellum was rare.The severity of CMBs was closely correlated with the severity of age,pervious stroke,hypertension and cerebral white matter hyperintensity.Conclusion CMBs are closely related with hypertension and cerebral microangiopathy,it may be a marker of advanced stage cerebral microangiopathy,guide ischemic stroke treatment.
