The diagnostic and differential diagnostic value of MR susceptibility weighted imaging in the hemorrhagic cerebral infarction

Objective To explore the clinical application value of susceptibility weighted imaging(SWI) in hemorrhagic cerebral infarction.Methods 430 cases of cerebral infarction in our hospital were enrolled.All patients were performed at 3.0T MRI scanner(Achieva;Philips Medical Systems,the Netherlands) in axial planes of conventional sequences(T1WI and T2WI),DWI and SWI.The presence or absence of hemorrhagic lesions were analyzed on T1WI,T2WI,DWI and SWI images.The differential diagnosis of hemorrhage in the cerebral infarction was analyzed using SWI.Results Of all patients,hemorrhagic cerebral infarction were diagnosed in 45 cases by SWI sequence,20 cases by T1WI,28 cases by T2WI and 31 cases by DWI.Conclusion Compared with MR conventional imaging(T1WI and T2WI) and DWI imaging,SWI can be able to detect more hemorrhagic lesions in earlier stage.SWI is superior to MR conventional imaging(T1WI and T2WI) and DWI imaging in the diagnosing hemorrhagic cerebral infarction,and then can be used as the first line,routine and follow-up examination for patients with acute cerebral infarction.
