As a new diagnostic method, DTI technology should be a routine examination for cerebrovascular diseases.3 DTI sequence should be added when the patient with cerebral ischemia has been examinated by routine MRI and found LA or cerebral infarction on acute stage in doubt. DTI can find hyper-acute and acute cerebral infarction immediately in order to treat the illness in time.4 DTI technology can reflect the mini-alter of alba formation pericerebral infarction with non-invasion in vivo. It can also appraise the degree of cerebral infarction and anticipate the result.
