Abstract: Objective To investigate the predictable value of susceptibility weighted imaging (SWI)in hemorrhagic transforma-tion (HT)of ischemic stroke.Methods 48 patients with ischemic stroke were involved.The presence and features of HT on CT, T1 WI,DWI and SWI were observed,as well as the distribution and signal features of cerebral microbleeds (CMBs),abnormal visi-bility of venules on SWI sequence.The correlation between those imaging findings and HT were analyzed.Results HT was detected in 19 of 48 patients (39.6%).The sensibility of T1 WI,DWI,SWI in detecting HT were 68.4%,36.8%,100%,respectively.HT was significantly associated with abnormal visibility of venules within the infarction region.The incidence of HT greatly increased with the aggravation of CMBs.Conclusion SWI can be a sensitive predictor for HT,and it’s helpful in making clinical strategy for ischemic stroke.
