Objective To study the value of artery spin labeling MRI in the diagnosis of cerebrovascular diseases. Methods The clinical data of 155 patients with cerebrovascular diseases who were admitted to the hospital from September 2015 to September 2017 were collected. Among them, there were 94 cases with acute cerebral infarction and 61 cases with transient ischemic attack. All the patients were examined by MRI, including the dynamic susceptibility contrast enhanced perfusion imaging (DSC) and arterial spin labeling technique. The Bowker test and Kappa value were used to analyze the consistency between the arterial spin labeling technique and the DSC parameters. Results For 94 patients with acute cerebral infarction, the Bowker values of arterial spin labeling technique with parameters of DSC CBF, CBV, MTT and TTP were 26.667, 26.667, 10.333 and 7.500, and the Kappa values were0.345, 0.345, 0.614 and 0.742, respectively. For 61 patients with transient ischemic attack, the Bowker values of arterial spin labeling technique with parameters of DSCCBF, CBV, MTT and TTP were 24.091, 24.091, 10.800 and 4.571, and the Kappa values were0.139, 0.139, 0.360 and 0.521, respectively. Conclusion The perfusion information in lesion area of patients with cerebrovascular diseases provided by arterial spin labeling MRI is basically consistent with the results of DSC, and it can provide valuable information for the diagnosis of cerebrovascular diseases.
