Abstract

Objective To investigate the magnetic resonance susceptibility weighted imaging (SWI) in the diagnosis and differential diagnosis of hemorrhagic infarction. Methods From October 2009 to October 2012, 215 patients with cerebral infarction underwent MR T1WI, T2WI, DWI and SWI scan. Analysis T1WI, T2WI, DWI and SWI differences in the detection rate of hemorrhagic infarction and differential diagnosis value of SWI on hemorrhagic infarction. Results SWI detected 45 cases of hemorrhagic infarction, T1WI detected 20 cases, T2WI detected 28 cases, DWI detected 31 cases. SWI detection rate was significantly better than the other methods (χ2 = 31.21, P0.05). Conclusion SWI can detect more cases of hemorrhagic infarction than MR conventional sequence (T1WI and T2WI) and DWI sequences, with a certain value of the differential diagnosis, can be the first-line method or the conventional sequence to check hemorrhagic infarction.
