Doctors find new way to predict recurrent stroke

New research from the University of Calgary shows that using a CT (computerised tomography) scan, doctors can predict if patients who have had a transient ischemic attack (TIA, a minor stroke), with neurological symptoms such as weakness or speech issues, are at risk for another more severe stroke. This vital information can help doctors decide if stronger medications should be used to prevent future episodes, or if a patient can be safely sent home. Currently, doctors can use a brain MRI (magnetic resonance imaging) scan to predict if a TIA patient is at high risk for a second stroke. Unfortunately, MRI machines are not immediately available for most people. In most health centers, including rural hospitals, CT scans are readily available.
