Radiation Absorbed Dose to the Basal Ganglia from Dopamine Transporter Radioligand 18F-FPCIT
Figure 3
Ratio of basal ganglia and bladder dose as a function of age. In three out of 16 subjects, basal ganglia (BG) dose exceeded that of the critical organ (urinary bladder) for 18F-FPCIT. In half of the subjects (), the BG dose exceeded 85% of the bladder dose. No aging effect on the BG dose was observed (, ).
