[Abstract] Objective: To observe the degree of cerebral ischemia and to predict the acute cerebral ischemia that may be happen by studying the brain anatomic microstructure anomalous.Materials and Methods: Do the systematic reviews on 1786 cases with cerebral ischemia in our hospital nearly three years. The first CT images of 385 cases present normal or suspicious, and reexamination CT and MRI within 7 days.Results: 385 cases that be diagnosised normal or suspicious by the first CT images happened new infarction after reexamination CT/MRI within 7 days. The brain anatomic microstructure anomalous on the first CT images can predict the occur of acute cerebral ischemic events. In addition, 5 patients were diagnosised abnormal on the first CT images, and presented normal on MRI (DWI) images that reexamination in 24 hours and 30 hours respectively.Conclusion: To evaluate the existence of cerebral ischemia by using of CT/MRI imaging methods.
