Abstract
Stroke is an injury to the central nervous system that is characteristically abrupt in onset & due to vascular insult. New ultrafast MRI methods have opened up the possibility of non invasively detecting & studying the time course of human ischemic pathophysiology. These include DWI which is sensitive to decrease in water self-diffusion within minutes of ischemia insult & is a marker for cellular energy failure. Conventional MR sequences can provide important information about the age of infraction. As recent infraction is not yet apparent on T1W1. FLAIR & T2WI can detect acute infraction but with better visualization by FLAIR images when it’s periventricular or cortical in position. chronic infractions appear as hyperintense area on T2WI & hypointense area on FLAIR. MRA is very important in assessing intracranial vessels, arterial main stem occlusion is easily be shown by MRA. MRA is very essential in decision of treatment. T2* can detect Hemorrhagic infractions efficiently. So, our stroke protocol includes the use of: -DWI for early detection of stroke (it holds considerable advantage over FLAIR & fast spin echo (FSE) imaging for identifying cerebral infarcts in the hyperacute and acute periods.
