Se calculó la dosis absorbida en la pared uterina y feto de una mujer con tres meses de gestación sometida a estudios renales con 99mTc-DTPA, 99mTc-DMSA y 99mTc-MAG3. Para el cálculo dosimétrico se usó la metodología MIRD y la representación antropomórfica de los órganos maternos debido a Stabin. La mayor dosis absorbida por la pared uterina y el feto se obtuvieron con el uso del 99mTc-MAG3. El órgano de la biocinética que contribuye con la mayor dosis es la vejiga. La menor dosis absorbida por la pared uterina y el feto se obtuvieron con el uso del 99mTc-DMSA. El órgano de la biocinética que contribuye con la mayor dosis es el "resto" de órganos.
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.
