Figure 5


Figure 5. Diagram on an arterial spin labelling(ASL) time course. In this graph, an example of two voxels having the same flow (60 ml 100 g–1 min–1) and relaxation characteristics, but different arrival time, is presented. The measured signal at a single inversion time of 1.5 s would result in a 12% lower {Delta}M signal in a voxel with delayed arrival of 500 ms (open square) as compared with a voxel with an arrival time of 200 ms (closed square).
