Abstract

When planning to undertake paraclinical investigations in pregnancy that involve ionizing radiation, a specialist should always think of the most appropriate test or intervention that carries minimal risks to both mother and fetus. A fetal radiation dose well below 50 mGy will be obtained in most cases. The risks of lethality, genetic damage/epigenetic change, teratogenicity, growth impairment or sterility are almost inexistent at this dose. Looking at the literature, one can see that old papers have shown an increased risk for malignancy, but this hasn’t been proven by the more recent studies. The linear no-threshold rule has been contradicted by recent scientific data with regards to malignancy risk. The same applies for iodinated mediums used as contrast. With the recent advances in medicine and the high expectations from the pregnant population, it has become obvious that in our days imaging in pregnancy is something that is frequently used. It is important to know what investigations can be performed in pregnancy with minimal effects on the fetus. A review of the literature has shown that the effects of a radiation below 50 mGy are likely to be negligible in pregnancy, with minimal or none risks in regards to the fetus. Magnetic resonance imaging (MRI) is the investigation of choice when it comes to pregnancy. The informed consent should always be sought and, when possible, the written consent.
