PET scans of brain during Ischemic Stroke

Description: Ischemic Stroke. Colored Positron Emission Tomography (PET) scans of the brain of a stroke patient. Twelve horizontal slices are shown, from deep brain (top left) to superficial (lower right). A lesion is seen in the left hemisphere (dark blue), an area of brain damage with reduced blood flow due to a narrowing or blockage. Color-coding is: high brain activity (white); low activity (blue). The stroke, or cerebrovascular accident (CVA), may cause brain damage such as loss of sight, speech or paralysis. PET scanning uses an injected radioactive tracer (H2.O15) to show variation in metabolic activity in the brain.
