RULES OF IMAGING IN CEREBRAL ISCHEMIC STROKE; REVIEW

Over 80% of strokes are caused by ischemic brain injury caused by a sudden decrease in blood supply. Large artery blockage occurs in 25-35% of strokes, and patients in this category frequently have severe neurological impairments. We conducted a narrative review due to 2021 for all relevant studies that were shown in one of the electrical databases such as; Medline. Recent advancements in stroke imaging enable near-real-time knowledge on several aspects of stroke pathology. The primary function of imaging is to rule out cerebral hemorrhage, characterize the ischemic zone, differentiate between infarct core and penumbra, and portray vascular health. CT and MRI are both reliable imaging modalities, each with their own set of advantages and disadvantages. Although CT is more readily available, MRI provides more information and is more sensitive to tiny infarctions.
