Brain death following cardiac arrest. Computed tomography (CT) scan of an axial section through the brain of a 28-year-old patient on life support for clinical brain death caused by a lack of oxygen (anoxia) after prolonged cardiac arrest following a diving accident. Here, diffuse hypodensity is visible in the posterior cerebral region, with hyperdensity of the brainstem, consistent with anoxia.
