The objectives of this article are to discuss the current evidence-based recommendations regarding radiation dose concerns, the use of iodinated and gadolinium-based contrast agents, and the comparative advantages of multimodality imaging (ultrasound, CT, and MRI) during pregnancy and lactation. We also discuss the use of imaging to evaluate pregnant trauma patients.
Maternal and fetal radiation exposure and dose are affected by gestational age, anatomic site, modality, and technique. The use of iodinated and gadolinium-based contrast agents during pregnancy and lactation has not been well studied in human subjects. Imaging should be used to evaluate pregnant trauma patients only when the benefits outweigh the risks.
本文旨在讨论当前有关辐射剂量问题、碘对比剂和钆对比剂使用以及在妊娠和哺乳期进行多模态成像（超声、CT 和 MRI）的比较优势的循证推荐。我们还讨论了使用影像学评估妊娠创伤患者的问题。
母体和胎儿的辐射暴露和剂量受胎龄、解剖部位、成像方式和技术的影响。在人体研究中，尚未充分研究碘对比剂和钆对比剂在妊娠和哺乳期的使用。只有当收益超过风险时，才应使用影像学来评估妊娠创伤患者。
