Caption

Stroke. Coloured Positron Emission Tomography (PET) scan of the brain of a stroke patient. This is a horizontal section through the brain. Colour- coding is: high brain activity (yellow to red); low activity (grey to blue). At centre left is a lesion (grey) showing an area of brain damage with reduced blood flow and lowered activity due to stroke. Stroke, or cerebrovascular accident (CVA), is a rupture or blockage of a blood vessel causing brain damage such as loss of speech or paralysis usually affecting one side of the brain. In PET scanning a radioactive tracer is injected into the blood to reveal metabolic activity in the brain.
