   Figure 1

   Time curves of a post-therapeutic blood dose assessment according to the EANM SOP (Lassmann et al. 2008) after administration of 3.6 GBq ¹³¹I (absorbed dose to the blood: 0.23 Gy). (A) Measured relative uptake and corresponding bi-exponential fits per liter of blood (filled circles, left axis) and of the whole body (filled squares, right axis). (B) Cumulative absorbed dose to the blood (solid line, left axis) and absorbed dose rate (dotted line, right axis).

   Figure 3

   Relative distribution of the absorbed dose coefficients (absorbed dose to blood) after radioiodine therapy in 66 patients after thyroid hormone withdrawal (hypothyroid) or after the use of recombinant human TSH (euthyroid) (Lassmann et al. 2007). The data are normalized to the minimal absorbed dose coefficient.
