Arterial segmentations from MR angiography overlaid onto coronal maximum-intensity projections of the PET data. As in Fig. 4, the maximum peak intensity over the whole PET time course is used, i.e., maximum intensity projection is performed over two dimensions: the anterior-posterior direction and the time dimension. The capillary tube (catheter) which was used for injection of 15O-water is also visible. The green arrow in S24 indicates the rete mirabile (see text)
