This extremely detailed scan looks directly at all the arteries and veins in your brain to assess whether there has been any narrowing or malformations of them. It also enables us to see tiny aneurysms (a bulging or ballooning in a weakened blood vessel wall).
Evidence of any of these could indicate a significantly increased risk of potentially catastrophic stroke or brain haemorrhage, although such early detection enables effective preventive treatment by modern radiology specialists.
