1 Μαΐ 2023 · Even though the fetus is more resistant to the radiation during the second and third trimester, a high dose of radiation (greater than 0.5 Gy or 50 rad) may result in adverse effects including miscarriage, growth reduction, IQ reduction, and severe mental retardation.
15 Νοε 2011 · Unborn babies are less sensitive during some stages of pregnancy than others. However, fetuses are particularly sensitive to radiation during their early development, between weeks 2 and 18 of pregnancy. The health consequences can be severe, even at radiation doses too low to make the mother sick.
There are radiation-related risks throughout pregnancy that are related to the stage of pregnancy and the fetal absorbed dose. Radiation risks are most significant during organogenesis and the early fetal period, somewhat less in the second trimester, and least in the third trimester;
15 Νοε 2021 · In this paper we consider exposures of pregnant women, chiefly in medical settings, review the effects of low, moderate and high dose radiation exposures on the embryo and foetus, and evidence for any difference in the response of pregnant women to radiation.
24 Απρ 2024 · Health effects to a fetus from radiation exposure depend largely on the radiation dose. Estimating the radiation dose to the fetus requires consideration of all sources external and internal to the mother's body: Most radioactive substances that reach the mother's blood can be detected in the fetus' blood.
1 Ιουλ 2007 · The potential biological effects of in utero radiation exposure of a developing fetus include prenatal death, intrauterine growth restriction, small head size, mental retardation, organ malformation, and childhood cancer.
The fetal risk to ionizing radiation is considered negligible during mammography. Dynamic contrast enhanced MRI is contraindicated during pregnancy, albeit safe in lactating patients. Reducing risk of radiation to the unborn child
