MESI technique can predict consistent blood flow changes across the thin skull — craniotomy boundary. (a) Relative blood flow changes estimated using the MESI technique in 3 pairs of regions across the boundary (Figure 4a). The change in blood flow is found to be similar for each pair of regions. (b) Relative blood flow changes estimated using the LSCI technique (at 5ms exposure) in 3 pairs of regions across the boundary (Figure 4a). The change in blood flow is not similar for each pair of regions. This difference is especially prominent over the vessel (Regions 1 and 2)
