Magnetic resonance imaging is being increasingly used to diagnose and follow up a variety of medical conditions in pregnancy, both for maternal and fetal indications. However, limited data regarding its safe use in pregnancy may be a source of anxiety and avoidance for both patients and their healthcare providers. In this review, we critically discuss the main safety concerns of Magnetic Resonance Imaging (MRI) in pregnancy including energy deposition, acoustic noise, and use of contrast agents, supported by data from animal and human studies. Use of maternal sedatives and concerns related to occupational exposure in pregnant personnel are also addressed. Exposure to gadolinium-based contrast agents and sedation for MRI during pregnancy should be avoided whenever feasible.
磁共振成像（Magnetic Resonance Imaging，MRI）在妊娠期间被越来越多地用于诊断和监测各种医学病症，包括母体和胎儿的病症。然而，关于其在妊娠期间安全使用的数据有限，这可能是患者及其医疗保健提供者感到焦虑和回避的原因。在这篇综述中，我们根据动物和人体研究的数据，批判性地讨论了磁共振成像（MRI）在妊娠期间的主要安全问题，包括能量沉积、声学噪声和对比剂的使用。还讨论了使用孕妇镇静剂和对孕妇职业暴露的担忧。在可行的情况下，应避免在妊娠期间使用钆基对比剂和 MRI 镇静。
