| Abstract: | Purpose:To evaluate the role of diffusion-weighed imaging in infarction.Materials and Methods:DWI or ADC-map and routine T_1WI and T_2WI were performed in 30 brain infarction.Results:All patients with acute infarction showed more marked signal intensity in DWI than in routine T_1WI and T_2WI.There are personal features in acute infarction,subactue infarction and chronic infarction.ADC changes regularly.Conclusion:Application of diffusion-weighted imaging may improve accuracy of diagnosis of brain infarction. |
