Delayed treatment outcomes compare with early CT thrombolysis if diffusion-perfusion mismatch is present

Evidence of brain injury is most prevalent in patients with physical symptoms and long duration of symptoms

An acute diffusion lesion is evident in one third of patients who have had a transient ischemic attack,1 and those patients may be at higher risk for stroke,2 according to a pair of studies presented at the 2007 International Stroke Conference in San Francisco in February.

MRI-assisted thrombolysis is as good as and perhaps better than CT-assisted thrombolysis, and it may be particularly valuable for patients treated outside of the prescribed 3-hour treatment window after stroke onset.

Two different advanced MRI techniques can help clinicians choose epilepsy patients who will favorably respond to surgical intervention, according to a pair of studies published in the October 2005 issue of Neurology.
