EPIDEMIOLOGY, DIAGNOSIS, MANAGEMENT AND PREVENTION OF STROKE: A NARRATIVE REVIEW.

Computed tomography (CT) scan of the brain is the most common form of clinical imaging procedure used in the treatment of stroke and Non-contrast CT Scans are usually the first step in imaging process. Diffusion-weighted magnetic resonance imaging (MRI) is the most sensitive imaging technique, it shows ischaemic changes very early and is effective in the evaluation of cerebral changes in ischaemic stroke. Magnetic resonance imaging is more precise in excluding intracranial hemorrhage and MRI with DWI is more accurate in the revealing acute ischemic stroke. Stroke treatment mainly focuses on restoring blood flow to the brain and treating stroke-induced neurological injury.
