Brain Ischemia: CT and MRI Techniques in Acute Stroke

摘要: Computed tomography (CT) and magnetic resonance imaging (MRI) protocols both provide excellent tools for evaluating acute ischemic stroke [1]. The choice of modality is driven by many factors, which must balance practical availability, clinical urgency, critical information required, range possible interventions under consideration. Although there controversy about method best, fortunately, methods can be effectively used refined to optimize diagnosis patient management [2,3]. Whether based on CT or MRI, comprehensive triage patients rational therapy individual vascular anatomy physiology. Parenchymal establishes the extent ischemia, MR angiography (CTA MRA) determines site occlusion interventional access options, perfusion studies a view collateral flow autoregulation. Refinements guidelines advanced techniques are still being worked out in trials, but these already play role practice.
