Stroke, MRI and 3D CT scans C016 / 6419
Stroke. Coloured composite image of a magnetic resonance imaging (MRI) scan of the brain and 2D and 3D computed tomography (CT) scans of the head and shoulders of a 48 year old patient after a cerebrovascular accident (CVA, or stroke). An infarct (area of dead tissue, pink and purple) is seen in the left hemisphere. The infarct is a result of ischaemia, a lack of blood flow to that area of the brain, caused by a blockage in a blood vessel. The blockage may be due to a thrombus (blood clot) or embolism (air bubble or loose blood clot). Strokes can be instantly fatal, or may pass unnoticed. Symptoms can include muscle weakness, behavioural changes or paralysis

EDITORS COMMENTS
This print showcases the intricate details of a stroke, providing a comprehensive view of the brain and head and shoulders region through magnetic resonance imaging (MRI) and computed tomography (CT) scans. The image focuses on a 48-year-old patient who has suffered from a cerebrovascular accident (CVA), commonly known as a stroke. The left hemisphere reveals an alarming infarct, characterized by pink and purple shades representing dead tissue caused by ischaemia – insufficient blood flow to that specific area of the brain. This lack of blood flow can be attributed to either a thrombus (blood clot) or embolism (air bubble or loose blood clot) obstructing the blood vessel. Strokes can have devastating consequences, ranging from instant fatality to unnoticed occurrences. Symptoms may manifest as muscle weakness, behavioral changes, or even paralysis. Understanding these symptoms is crucial for timely diagnosis and treatment. Through this powerful visual representation, we gain insight into the complex nature of strokes and their impact on our bodies. It serves as a reminder of both the fragility and resilience within our anatomy while emphasizing the importance of medical advancements in diagnosing conditions like strokes accurately. ZEPHYR/SCIENCE PHOTO LIBRARY's expertise in capturing such detailed images allows us to delve deeper into understanding various medical conditions affecting individuals worldwide.
