Fig. 3

The graphical layout demonstrating uptake foci in a liver carrying a 111In-octreotide positive tumour (111In-octreotide(+)), the tumour is indicated (T). The additional graphs, appearing on the panels at the lower right, show the number of normalized uptake foci (y-axes), plotted against threshold index (ThI) (x-axes). In a liver with 111In-octreotide-positive tumours, the distribution of uptake foci will be shifted towards higher ThI, due to the merging of uptake foci in the tumour area (a–d)
