Ischemic stroke is the second frequent cause of death worldwide. Some patients have transient symptoms of neurological defect without parenchymal damage, irreversible cerebral tissue injury happens in someone else. How to discriminate TIA from acute stroke needs further study. This study uses muti-modal MRI scaning to investigate the difference of plaque characteristics in Middle Cerebral Artery (MCA) between patients with infarction and transient ischemic attack (TIA), and to explore the predictive model for infarction region and neurological impairment.
