value of Magnetic Resonance Diffusion Weighted Imaging in Diagnosis of Cerebral Infarction

Objective To study the significance of the magnetic resonance diffusion weighted imaging(DWI) technology in diagnosis of cerebral infarction.Methods DWI and conventional MRI(Magnetic Resonance Imaging) scan are applied in examination of 46 patients with cerebral infarction.Then,analysis of the results are made.Results 13 hyperacute lesions show significantly high signals through DWI with no obvious abnormal changes in T2WI and T2Flair signals.22 patients who are in the acute phase of cerebral infarction lesions show high signals through DWI with high or slightly high T2WI and T2Flair signals and the detection rate of 100%.7 subacute cases show slightly high signals through DWI,which are lower than the signal of the acute phase.T2WI and T2Flair of 7 subacute cases show high signal.4 DWI cases are in the chronic phase and show equal signals or low signals with significantly high T2WI signals.Conclusion With its characteristic of high accuracy,DWI diagnosis of early cerebral infarction is significantly superior to conventional MRI.
