Cerebrovascular 4D Flow MRI

Cerebrovascular 4D flow MRI focuses on intracranial flow in healthy controls and disease settings including arteriovenous malformations, vein of Galen malformations, cerebral aneurysms, and intracranial atherosclerotic disease.

Overview

Cerebrovascular applications carry 4D flow MRI into intracranial circulation.

Intracranial flow measurement extends 4D flow MRI expertise.

Studies span healthy-comparison work and cerebrovascular disease settings.
