Undergoing CT in Pregnancy-Drink Barium Sulphate As An Internal Shield!
"Study used a phantom to prospectively examine the attenuating effect of barium sulfate as an internal shield to protect the fetus. The control radiation dose was 3.60 mSv ± 0.54 (standard deviation) with the water slab at near field, where the uterus dome is at near term, and 0.507 mSv ± 0.07 with the water slab at far field, the uterus position during early gestation. Scattered radiation was attenuated 13% and 21% with 2% barium sulfate and 87% and 96% with 40% barium sulfate, as calculated in the near and far fields, respectively, and 99% with the 1-mm lead sheet. Study results in the phantom experiment suggest that fetal irradiation during maternal chest CT can be reduced substantially with barium shielding. "
