Screening for arteriovenous malformation (AVM) requires a complete neurological as well as physical examination. As soon as people experience symptoms, or observe them in loved ones, they are encouraged to seek a diagnosis at a center such as Florida Hospital’s Neuroscience Institute that utilizes the most advanced brain imaging technology.
Tests for Arteriovenous Malformation (AVM)
Cerebral Angiogram –a special dye is injected through a catheter to reveals in an x-ray any blockages to blood is flowing in the brain.
Cranial MRI – magnetic resonance imaging scans of the head create detailed pictures of the brain; a special dye is also used for some MRI exams.
Electroencephalogram (EEG) – electrical impulses between brain cells are measured using electrodes placed on the head.
Head CT Scan – the computed tomography scan takes many x-rays in a “spiral” scan of the brain allowing doctors to create a three-dimensional view of the head.
Magnetic resonance angiography (MRA) – the test is an MRI of the blood vessels, but is non-invasive unlike the cerebral angiogram that requires use of a catheter.
