[Abstract] Objective: To evaluate acute ischemic cerebral apoplexy brain damage by diffusion tensor imaging (DTI) and arterial spin labeling (ASL) at 3.0 T MRI.Materials and Methods: Twenty-five cases with acute ischemic cerebral apoplexy, there were 5 cases of superacute stage, 16 cases of acute stage and 4 cases of subacute stage. All patients underwent DTI and ASL imaging techniques. DTI and ASL images in every period were observed and performed post-processing using professional software to rebuild the corticospinal tract, and FA, ADC and rCBF values of the infarction and mirror areas of magnitude were measured. Difference of FA, ADC and rCBF values between infarction and mirror areas were analyzed by t-test. Correlation between FA, ADC and rCBF values was analyzed by multivariate partial correlation analysis.Results: FA, ADC and rCBF values of infarct areas in all patients were decreased evidently (P<0.05), correlation of FA, ADC and rCBF values in infarction area had no obvious significant difference (P>0.05). The Spearman rank correlation analysis of three periods respectively FA, MD and rCBF values of infarction areas were no obvious difference (P>0.05).Conclusions: DTI and ASL could reflect the situation infarcts perfusion early and the relationship between the infarction and white matter fiber bundles. DTI and ASL could be used to predict the degree of acute isschemic cerebral apoplexy brain damage.
