The approach to imaging in pregnancy is unique, as it is essential to minimize radiation exposure to the fetus. Ultrasonography and magnetic resonance imaging are the chief modalities for evaluation of the pregnant patient with abdominal pain. Use of computed tomography should not be delayed when there is a need for early diagnosis. This article discusses test selection and underlying reasoning, with a description of common imaging features of different causes of acute abdominal pain in pregnancy. Also discussed are current evidence-based recommendations for the use of iodinated and gadolinium-based contrast agents and the importance of patient counseling.
孕期的成像检查方法独具特色，因为将胎儿所受辐射暴露降至最低至关重要。超声检查和磁共振成像（MRI）是评估孕期腹痛患者的主要方式。当需要早期诊断时，不应延迟使用计算机断层扫描（CT）。本文讨论了检查选择及潜在的推理依据，并描述了孕期不同原因引起的急性腹痛的常见成像特征。还讨论了目前关于使用碘化造影剂和钆基造影剂的循证医学建议以及患者咨询的重要性。
