Absolute permeability (milliliters per 100 g per minute) maps for the reference standard 90- to 240-second delayed acquisition and for the 0- to 90-second first-pass acquisition with delay correction, the 30- to 90-second first-pass acquisition with delay correction, and the 0- to 90-second first-pass acquisition without delay correction. BBBP values calculated from the delay-corrected 30- to 90-second first-pass acquisition overlapped with the ones calculated from the reference standard 90- to 240-second delayed acquisition in the ischemic parenchymal tissue and were slightly underestimated in the nonischemic parenchymal tissue. The delay-corrected first-pass did not show the overestimation of BBBP values in the penumbra that were seen with the first-pass acquisition without delay correction.
