False colour nuclear magnetic resonance (NMR) image of an axial section of the brain of a person suffering from a cerebral infarction. The infarct (area of dead tissue) appears as the white & yellow area in the left cerebrum (right on image),and is caused by an obstruction in the middle cerebral artery with the resulting interruption in blood supply. Such an event (termed a cerebro- vascular accident) is often the cause of a stroke,a sudden attack of weakness affecting one side of the body. The initial obstruction may be due to a clot (thromosis),a dislodged clot blocking an artery (embolism) or haemorrhage from a weakened arterial wall | |
