Description

Red outlined areas of this CT scan show the stroke in the brain. A stroke, sometimes referred to as a cerebrovascular accident (CVA), cerebrovascular insult (CVI), or colloquially brain attack is the loss of brain function due to a disturbance in the blood supply to the brain. This disturbance is due to either ischemia (lack of blood flow) or hemorrhage. As a result, the affected area of the brain cannot function normally, which might result in an inability to move one or more limbs on one side of the body, failure to understand or formulate speech, or a vision impairment of one side of the visual field. A stroke is a medical emergency and can cause permanent neurological damage or death. X-ray computed tomography (x-ray CT) is a technology that uses computer-processed x-rays to produce tomographic images (virtual slices) of specific areas of the scanned object, allowing the user to see what is inside it without cutting it open. The term computed tomography alone (or CT) is often used to refer to x-ray CT. Older and less preferred terms that also refer to x-ray CT are computed axial tomography (CAT scan) and computer-assisted tomography. X-ray CT is a form of radiography. No date, location or sex was given.
