CT Angiography - Cerebral / Head with Contrast

It is an imaging test that uses a rotating beam of X-rays to create detailed 3-dimensional images of blood vessels in the head and neck. A contrast agent is used for better visualization of the arterial anatomy to find out disease or related conditions, such as aneurysms, blockages, blood clots, tumours, vessel tears and disorganized blood vessels. Your doctor may advise this test to find out the cause of dizziness, fainting, double vision, difficulty pronouncing words, headache, hearing loss, and stroke.
