Stroke, MRI scan
Stroke. Coloured magnetic resonance imaging (MRI, left) and computed tomography (CT, right) scans of axial sections through the brain of a 58-year-old patient, showing the damage (blue) caused 10 hours and 24 hours respectively, after a cerebral infarction. A stroke, or cerebrovascular accident (CVA), is the rapid loss of brain function due to disturbance in the blood supply to the brain. A cerebral infarction is an ischemic stroke, whereby lack of blood flow occurs when a blood vessel that supplies a part of the brain becomes blocked, or leakage occurs outside the vessel walls. Here, the right middle cerebral artery (MCA) was affected, causing damage to the areas of the brain supplied by that artery and leading to total paralysis of the arm, leg, and

EDITORS COMMENTS
This print from Science Photo Library showcases the devastating effects of a stroke on the human brain. The coloured magnetic resonance imaging (MRI) and computed tomography (CT) scans reveal the progressive damage caused by a cerebral infarction in a 58-year-old patient. In just 10 hours, the blue hues indicate areas of compromised blood supply, while after 24 hours, the extent of damage becomes even more apparent. A stroke, also known as a cerebrovascular accident (CVA), occurs when there is an interruption in blood flow to the brain, resulting in rapid loss of brain function. This particular case involves an ischemic stroke where blockage or leakage affects the right middle cerebral artery (MCA). As a consequence, paralysis engulfs not only one's arm and leg but also total motor control. The intricate details captured by this image highlight both the biological and medical aspects associated with strokes. It serves as a reminder that strokes can have profound consequences on our anatomy and circulation system. Through diagnostic imaging techniques like MRI and CT scans, healthcare professionals gain valuable insights into identifying such conditions accurately. Science Photo Library continues to provide invaluable resources for researchers, educators, and medical practitioners alike through their vast collection of scientifically accurate visual content.
