In spite of a growing number of radiological scans in pregnant women there is still a high level of uncertainty concerning radiation exposure to the fetus. At the same time, the risk of fetal radiation injury is frequently overestimated. This entails an avoidable fear in the pregnant patient and may delay urgently required imaging and thus lead to an increased risk for maternal and fetal health. As a consequence, radiological scans in pregnant patients do not only require a thorough medical check but also a careful estimate of the specific radiation exposure to the fetus. The previous first part of the article described the legal requirements in Germany, the technical exposure and pharmacological risks for the pregnant woman and the fetus. The current second article focuses on the risk analysis for examinations with ionizing radiation and will provide recommendations for typical indications for maternal and fetal imaging.
尽管孕妇接受放射检查的数量不断增加，但关于胎儿辐射暴露仍存在高度不确定性。与此同时，胎儿辐射损伤的风险常常被高估。这给孕妇带来了不必要的恐惧，可能会延误急需的影像学检查，从而增加母婴健康风险。因此，对孕妇进行放射检查不仅需要全面的医学检查，还需要仔细评估胎儿的具体辐射暴露情况。本文的前半部分描述了德国的法律要求、孕妇和胎儿的技术暴露及药理学风险。当前的第二篇文章重点关注电离辐射检查的风险分析，并将针对母婴影像学的典型适应证提供建议。
