A stroke can be defined as a neurological deficit attributed to an acute focal injury of the central nervous system (CNS). There are two types of strokes, and these include ischemic and hemorrhagic. An ischemic stroke is caused by a lack of blood flow to the brain. A hemorrhagic stroke is due to a burst or rupture of a blood vessel within the brain. Computed tomography (CT) is the ideal imaging study done when diagnosing strokes in patients. The importance of quickly diagnosing a stroke and determining which type the person has experienced is one reason why CT scans are effective for stroke diagnosis. This allows the patient to get the quickest care possible. When using CT to diagnose a stroke it can be done without contrast, as an angiography, or as a perfusion study. The speed, availability, and diagnostic capabilities of CT scans make them valuable tools in the diagnosis and treatment of stroke patients.
