The Chinese word for cranial MRA scan is cranial vascular magnetic resonance imaging scan, which is a type of MRI exam that examines the blood vessels in the skull. The diagnosis of cerebral infarction, cerebral hemorrhage and cerebrovascular malformation can be clarified by cranial MRA scan. MRI is the general cranial MRI scan, which is used to examine brain tissue damage, and is also known as MRI. In the case of cerebrovascular accidental disease, both cranial MRA plain scans and cranial MRI plain scans are examined. The combination of these two tests can examine both the condition of vascular lesions and the damage to brain tissue caused by cerebrovascular accident disease.
