Examining the association of diagnostic imaging and clinical outcome in patients with acute ischemic stroke


  • The use of computed tomography (CT) alone is not inferior to the additional use of magnetic resonance imaging (MRI) in patients with acute ischemic stroke.

Why this matters

  • Diagnostic imaging of acute ischemic stroke requires initial CT, which is often followed by additional MRI.  

  • The association between diagnostic imaging strategy and clinical outcomes is not well understood and elucidating it could allow clinicians to clarify which patients would benefit from both CT and MRI, or just CT alone.
