Abstract: Objective To investigate the decisional value of susceptibility weighted imaging(SWI) in intravenous thrombolytic therapy to acute cerebral infarction.Methods According to cerebral microbleeds(CMBs) by SWI, 35 cases of acute cerebral infarction in window-time random were divided into experimental group(14 cases) with CMBs and control group(21 cases) without CMBs.After intravenous thrombolysis, the number of hemorrhagic transformation(HT) was counted by SWI, and statistic difference was compared between the experimental group and the control group(P<0.05).Results After intravenous thrombolytic therapy of acute infarction,12 cases with HT among experimental group, and only 2 cases with HT among control group, there was significant statistically difference between two groups(P<0.05).Conclusion SWI sequence has greater sensitivity in detecting CMBs,and can also assess the state of blood brain barrier(BBB) and vascular wall indirectly.It plays a very important role in giving a decision in the treatment of intravenous thrombolytic with window-time.
