MRI Aids Assessment of Stroke Risk After Minor Stroke or TIA

Abstract

To examine factors that might predict which patients with early ischemic neurologic symptoms are at very high risk for recurrence, researchers prospectively tested the usefulness of early magnetic resonance imaging (MRI) for predicting the risk for recurrent events among 120 consecutive patients evaluated at one hospital. All patients were examined within 12 hours of onset of symptoms of minor stroke (a score of 1–3 on the National Institutes of Health Stroke Scale) or transient aphasia or hemiparesis lasting longer than 5 minutes.
