What is the use of MRI in stroke evaluation?
MRI has been used for in-hospital stroke evaluation since 1999. It is used to provide diagnostic yield of follow-up brain imaging and can detect acute ischemic stroke even when the initial MRI is negative. It is also particularly helpful in evaluating patients with low-risk TIA and mild neurological symptoms. Confirming the diagnosis of acute ischemic stroke with brain imaging may help with patient education and prognostication, which in turn may promote adherence to a prescribed prevention regimen.
