Abstract Abstract: Objective: To investigate the sensitivity of susceptibility-weighted imaging(SWI) in displaying atery thrombosis in ischemic stroke, and evaluate the role of SWI in the assessment of arterial thrombosis in ischemic stroke. Methods: Thirty-six patients(19 males, 17 females, age 20~83 years, average 65 years) with acute cerebral infarction(within 24 hours after clinical onset) performed and followed up with SWI. The presence of correlated atery thrombosis within the infarction were observed, the correlation between the extent of the correlate aterial thrombosis. NIHSS was analyzed. Results: The correlated aterial thrombosis was revealed by SWI in 27 out of 36 massive cerebral infarctions, the proportion was 75%. Seventeen were signifcantly showed(the length of aterial thrombosis >3cm), 10 were midly showed on the SWI(the length of aterial thrombosis <3cm). There was a significant positive correlation between the severe ischemic stroke aterial thrombosis displayed in the SWI and the NIHSS scores(rs=0.782, P<0.01). Conclusion: SWI was sensitive in detecting the atery thrombosis in infarction, which can be used to predict the evolution of ischemic stroke, which was helpful in guiding the clinical treatment.
