Fig. 2

Whole-body quantitative planar scans for one subject (subject C in Table 3) for a single cycle from 0 to 96 h (approx.). The estimated retained radioactivity is estimated to be 8878, 3456, 1865 and 614 MBq for each of the time points, corresponding to 100, 39, 19 and 7 % retained, respectively. The calibration standard seen in Fig. 1 is removed by the software before the determination of the total radioactivity retained in the subject
