Evaluation of multimodal CT or MRI for treatment of ischemic stroke with unknown time of onset


  • Computed tomography (CT) and magnetic resonance imaging (MRI) showed similar safety and efficacy when evaluating for intravenous thrombolysis (IVT) in acute ischemic stroke (AIS) within an unknown or extended time period, but CT resulted in shorter procedure times.

Why this matters

    Safety and efficacy of IVT in patients with AIS and unknown symptom onset time has been shown, but there is no consensus on the preferred imaging protocol for patient selection; identifying an optimal imaging protocol will likely improve patient outcomes.
