Figure 4.

DWI (b = 1,000 s/mm²), sqBOLD parameter maps (R ₂′, DBV, and [dHb]) and CBF maps are presented for a single axial slice in an example patient. Core (blue), growth (orange), and contralateral (yellow) tissue outcome ROIs are displayed on the spin‐echo image of the sqBOLD acquisition. Patient P03 (male, 79 years old, NIHSS = 14, IV thrombolysis at 1 hr 24 min postonset) was scanned on presentation (2 hr 20 min postonset) and again at 24 hr [Color figure can be viewed at http://wileyonlinelibrary.com]
