Greater lesion growth rate in patients with shorter time gap between symptom onset and imaging

Takeaway 

  • Patients who had initial imaging •1.85 hours after symptom onset had greater lesion growth 24 hours later, after recanalization, than patients who had initial imaging ≥1.85 hours after symptom onset.

Why this matters

    The impact of time gap from symptom onset to initial imaging on stroke outcomes has not been investigated, although evidence of rapid, early lesion growth could affect stroke treatment.
