New Fetal Radiation Doses for 18F-FDG Based on Human Data

Current standard values of fetal dosimetry deriving from F-18-FDG injection in pregnant women are estimated from animal data. The present communication offers a revision of fetal dosimetry values calculated from recently published human data, in which fetal F-18-FDG uptake was directly observed in vivo. The final doses were obtained from the observed time-integrated activity coefficients and a new generation of anthropomorphic voxel-based pregnancy phantoms.
