The Application Value of Susceptibility Weighted Imaging in Patients with Early Intracerebral Hemorrhage and Hemorrhagic infarction

Objective:To evaluate the application value of susceptibility weighted imaging (SWI) at 1.5 Tesla (t) MRI in patients with hyper acute intracerebral hemorrhage (ICH) and hemorrhagic infarction (HI).Method: Collected twenty-five patients (average age:58) with hyper acute ICH and twenty-two patients (average age:54) with acute HI from 2010.2 to 2011.11.All cases underwent T1WI, T2WI, FLAIR, DWI and SWI scan with 1.5t MRI scanner (GE Signa 1.5T EXCITE HDMR).ICH times of accident are in 6 hour, HI times of accident are in 24 hour.Results:The display rate of intracerebral hematomas was 80% (20/25 cases) in T2WI, but was 100% (25/25cases) in SWI.All cases showed the scope of bleeding greater in SWI than conventional sequence.The display rate of hemorrhagic infarction was 9% (2/22cases) in T1WI, but was 100% (22/22 cases) in SWI. Conclusion:The SWI sequence has greater help in the diagnosis of early stroke type and hemorrhagic infarction than conventional MR sequences.SWI has great guide significance for clinician treatment.
