A perfusion imaging tool to assess the quality of the collateral blood flow in hyperacute stroke

Takeaway

  • Intravoxel incoherent motion (IVIM) perfusion imaging is a promising tool to assess the quality of the microvascular collateral blood flow in hyperacute stroke.

  • The IVIM penumbra perfusion lesion might be a marker of stroke severity at baseline and might be counted to the stroke core when present.

Why this matters ?

  • The importance of brain imaging in patients with acute ischemic stroke is increasing; the assessment of the quality of the collateral blood flow with current neuroimaging methods is limited.
