The value of diffusion-weighted imaging with 3.0T MR in the diagnosis of acute cerebral infarction

Objective:To explore the value of DWI in the diagnosis of acute cerebral infarction. Methods:Thirty-one Patients with acute cerebral infarction(hyperacute cerebral infarction in 3 cases and acute cerebral infarction in 28 cases) were examined with 3T MRI DW sequence.The imaging was studied,the ADC value was calculated and compared with contralateral normal brain tissue. Results:(1)Thirty-nine acute cerebral infarction lesions were found in 31 patients.All ischemic lesions were demonstrated with hyperintensity on DWI.(2)The higher the b value,the better the effects of diffusion and imaging.(3)The value of ADC of the lesions decreased than that of the contralateral normal area. Conclusion:DWI is of a most sensitive and accurate method in the diagnosis of acute cerebral infarction.
