Differences in the S value between male and female murine model for diagnostic, therapeutic and theragnostic radionuclides.

The aim of this work was to calculate S values for 99 mTc, 67 Ga, 68 Ga, 18 F, 223 Ra, 166 Ho, 90 Y, 161 Tb 131 I and 177 Lu, using a mouse phantom (MOBY) standard and considering the anatomic sizes from males and females, the simulation of radiation transport was performed with GATE/Geant4 platform. This indicates that in the internal dosimetry the use of a customized geometry is relevant for each gender and a standard model is not a good choice.
