The use of magnetic resonance imaging (MRI) during pregnancy is on the rise due its ability to provide detailed cross-sectional anatomy without ionizing radiation. Despite the favorable radiation profile, theoretically concerns regarding the safety of MRI and gadolinium-based contrast agent (GBCA) administration have been raised. Currently there are no studies that have shown any attributable harms of MRI during any trimester of pregnancy although prospective and longitudinal studies are lacking. GBCA administration may be associated with a slightly higher rate of neonatal death, although this is based on a single, large cohort study. Understanding the available evidence regarding MRI safety during pregnancy in the context of current society guidelines will help the radiologist serve as a valuable resource to patients and referring providers.
由于磁共振成像（MRI）能够提供无电离辐射的详细的横截面解剖结构，因此在怀孕期间的使用越来越多。尽管辐射情况良好，但理论上仍对 MRI 和基于钆的造影剂（GBCA）给药的安全性表示担忧。目前，尚无研究表明在妊娠的任何三个月期间 MRI 有任何可归因的危害，尽管前瞻性和纵向研究尚缺乏。尽管这基于一项大型的单一队列研究，但 GBCA 给药可能与新生儿死亡的略高发生率相关。了解当前社会指南中怀孕期间 MRI 安全性的现有证据将有助于放射科医生为患者和转诊医生提供有价值的资源。
