VASQUEZ-ARTEAGA, Marcial et al. ABSORBED DOSE IN THE UTERINE WALL AND FETUS BY^99m Tc ADMINISTRATION (DTPA, DMSA and MAG3). Momento [online]. 2021, n.62, pp.32-42.  Epub Jan 30, 2021. ISSN 0121-4470.  https://doi.org/10.15446/mo.n62.84271.

The absorbed dose in the uterine wall and fetus of a woman with three months of gestation submitted to renal studies with 99mTc-DTPA, 99mTc-DMSA, and 99mTc-MAG3 was calculated. For the dosimetric calculation, the MIRD methodology and the anthropomorphic representation of the maternal organs due to Stabin were used. The highest dose absorbed by the uterine wall and the fetus were obtained with the use of 99mTc-MAG3. The organ of biokinetics that contributes to the highest dose is the bladder. The lowest dose absorbed by the uterine wall and the fetus were obtained with the use of 99mTc-DMSA. The organ of biokinetics that contributes the highest dose is the "rest" of organs.

Keywords : MIRD dosimetry; uterine wall-fetus; ^99mTc-(DTPA; DMSA; and MAG3).
