FIGURE 3. Analysis of quantitative kinetics of [¹²⁴I]FIAU in various organs of cats early (A) and late (B) after systemic administration of 37 MBq [¹²⁴I]FIAU. Values are averaged over three animals. Brain showed lowest [¹²⁴I]FIAU uptake of all organs throughout entire measurement. Brain symbols (•) represent PET frames acquired sequentially. For clarity in graphs, not all symbols for each frame are depicted for other organs. p.i. = after injection.
