For the case of 18F-FDG, a dose was given with no information about placental transfer of the radiopharmaceutical. Recent publications have reported quantitative values for maternal and fetal uptake of 18F-FDG in primates and new values for 18F-FDG kinetics. In this article, these data are applied to give radiation dose estimates for the fetus at all stages of pregnancy for 18F-FDG. The recommended values are 2.2 × 10−2 mGy/MBq in early pregnancy, 2.2 × 10−2 mGy/MBq at 3-mo gestation, 1.7 × 10−2 mGy/MBq at 6-mo gestation, and 1.7 × 10−2 mGy/MBq at 9-mo gestation. %U https://jnm.snmjournals.org/content/jnumed/45/4/634.full.pdf
