In an emergency situation like a stroke, it's important for doctors to first confirm the type of stroke to provide the appropriate treatment. Imaging tests like a CT scan or MRI can help determine the type of stroke; blood flow tests like cerebral angiography, can help evaluate the size and location of blockages.
Even if the physical symptoms of a stroke are obvious, brain scans should also be carried out to determine: 1  if the stroke has been caused by a blocked artery (ischaemic stroke) or burst blood vessel (haemorrhagic stroke) 2  which part of the brain has been affected. 3  how severe the stroke is.
