Aim
To investigate whether bolus delay-corrected (BDC) mean transit time (MTT) MRI perfusion measures enable superior delineation of the ischemic penumbra in acute stroke.

Conclusions
Uncorrected perfusion lesion volumes (MTT, iMTT) overestimated the extent of ischemic injury. BDC perfusion measures (cMTT) correlated more accurately with final lesion volume and clinical outcome. Such measures offer an improved estimation of the final infarct size and improve our understanding of the ischemic penumbra.
