Abstract

Objective To evaluate the diagnostic value of DWI in acute cerebral infarction.Methods Twenty-two patients with cerebral infarction(hyperacute infarction in 3 cases and acute infarction in 19 cases) were examined with T_1WI,T_2WI and DWI sequences.The contrast of lesions,boundary and extent on all images were compared.ADC and rADC of the lesions were calculated.Results ①The contrast of lesions,boundary and extent on DWI were superior to convertional T_1WI and T_2WI.②The value of ADC and rADC of the lesions decreased in all cases.Conclusion DWI is of the most sensitive,and it has great value in the diagnosis of acute cerebral infarction.
