Boxplots comparing the mean transit time (MTT -- a), the cerebral blood flow (CBF -- b) and the cerebral blood volume (CBV -- c) for five different regions of interests (ROIs) between diseased and healthy dogs. All values are normalized with respect to the Centrum semiovale and were computed using a choice of alpha = 0.8. We clearly see a tendency of a higher mean transit time and a lower cerebral blood flow for diseased dogs, most prominently for the Hippocampus and the Thalamus. Overall the boxplots show a very similar behavior as for the value alpha = 0.3. The properties of the box plots are identical to Fig. 4.
