Arterial Spin Labeling (ASL) fMRI: Advantages, Theoretical Constrains and Experimental Challenges in Neurosciences
Figure 2
(a) Three-vessel encoding of vasculature above the Circle of Willis. In the labeling plane shown on the right, the ACA is well confined to the midline with the corresponding flow territory represented in pCASL perfusion maps as green. The territories supplied by the insular branches of the MCAs are also well labeled (shown in red and blue). Figure taken without modification from Wong [25]. (b) Selective encoding of three branches of the ACA using super-selective pCASL [26]. Top row shows TOF image and the corresponding saggital maximum intensity projection with the branches of the ACA color coded. The bottom row shows perfusion-weighted images of the territories fed by each vessel. Figure was taken without modification from Helle et al. [26].
