Figure 3.

Baseline and functional Turbo-DASL results from two rats, anesthetized with isoflurane (left) and α-chloralose (right). Gray scale background maps (except the anatomical T₁-weighted image a) were quantitative CBF values obtained without and with diffusion gradients (b and c, respectively), and TT values without and with diffusion gradients (d and e, respectively). Color maps overlaid on baseline images were percent changes of active pixels responding to forepaw stimulation. On the anatomical T₁-weighted images (a), the black box indicates the 3×3 pixel ROI in the contralateral area, which will be used for further data analysis. Arrows indicate one large arterial vessel region, where the diffusion gradient of 50 s/mm² changed the computed baseline CBF and TT.
