Panel a shows the average maps of two test groups as well as the mean difference map derived from those average images. The colour maps of the two average maps are scaled to the same maxima and minima. The arrow indicates blood flow of the unwarped and standardized aortic artery maps. Aortic arch, descending aorta and inner as well as outer curvature are marked. Panel b depicts the resulting normalized difference map after permutation testing as well as the thresholded difference map, where the threshold t has been derived from the maximum permutation distribution using the significance level α = 0.05. Panel c shows the same results with the addition of the cluster-enhancement
