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.
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 risk of each effect depends on the gestational age at the time of exposure, fetal cellular repair mechanisms, and the ...
25 Απρ 2022 · Concerns about harm to the fetus and mother can make decisions to image difficult for patients and clinicians. However, risk is often lower than expected and, especially in many acute situations, is outweighed by the benefit. This article outlines the potential fetal and maternal risks from commonly used imaging modalities.
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;
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
1 Μαΐ 2023 · Understanding of consequences of radiation exposure on a fetus, degrees of fetal radiation exposure by each imaging modality, and techniques on reducing fetal radiation exposure is vital in choosing the best diagnostic imaging modality.
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.
