How do we diagnose an AVF?
Magnetic resonance angiography, or MRA, is an important tool for diagnosing and following brain AVFs. MRA uses a powerful magnetic field to produce images of the brain. MRA is often used to diagnose or follow brain AVFs and allows physicians to better evaluate the arteries within the brain. MRA does not produce radiation and is not associated with radiation risks.
Computed tomographic angiography, or CT scans, can also be used to diagnose AVFs. CT scanners use a series of x-rays and powerful computers to create detailed images of the brain and its blood vessels.
In angiography, a special dye is injected through an IV line, and x-rays of the brain are taken at multiple angles in order to see the arteries within the patient’s brain. Angiography is usually performed by a specially trained neuroradiologist or neurosurgeon.
