Fig. 6

Average image of percentage differences between AB- and ZTE-MRAC CBF calculated from all individual percentage change images. Red and blue indicate higher and lower values in the AB-MRAC method, compared with the ZTE-MRAC method, respectively. The parietal to occipital region shows higher CBF values with the AB-MRAC method compared with the ZTE-MRAC method, although the difference was less than 5%. Most of other brain regions showed very close regional CBF values, less than ± 2%
