Human head, MRI and 3D CT scans
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) 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 human head, revealing the devastating aftermath of a stroke. The image is a composite of various scans including a magnetic resonance imaging (MRI) scan of the brain and 2D and 3D computed tomography (CT) scans of the head and shoulders. The focal point lies in the left hemisphere where an infarct, depicted as an area of pink dead tissue, serves as a stark reminder of the consequences that can arise from ischaemia - a lack of blood flow to that specific region caused by blockage in a blood vessel. This blockage may be attributed to either a thrombus or embolism. Strokes are unpredictable; they can strike instantaneously with fatal outcomes or go unnoticed until symptoms manifest themselves. These symptoms encompass muscle weakness, behavioural changes, and even paralysis. In this particular case, we observe how this cerebrovascular accident has affected the cerebral cortex within one hemisphere. The complexity behind diagnosing such conditions becomes evident through this visual representation. Displayed against an intense black background, this print not only captures our attention but also highlights the importance of understanding vascular health and its impact on our overall well-being. It serves as both an educational tool for medical professionals and individuals seeking knowledge about strokes' repercussions on our intricate organ systems.
