Educational Pearls:


  • Modified Rankin Score:  measure of disability often used to qualify outcomes following stroke  = no disability, 6=dead, 0-1 indicate good outcome)
    • 0-6 Scale
    • 0-1 indicative of good outcome
  • ASPECT score: uses CT to quantify the extent of changes in the brain due to ischemia
    • 0-10 Scale
    • 10 areas are assessed on non-contrast CT to assess for early stroke changes
    • -1 for each area with these findings
    • 8-10 is indicative of better outcomes
