妊娠期和哺乳期诊断影像指南2016

The American College of Obstetricians and Gynecologists’ Committee on Obstetric Practice makes the following recommendations regarding diagnostic imaging procedures during pregnancy and lactation:

美国妇产科医师协会产科实践委员会对妊娠期和哺乳期诊断影像的使用提出如下建议：

Ultrasonography and magnetic resonance imaging (MRI) are not associated with risk and are the imaging techniques of choice for the pregnant patient, but they should be used prudently and only when use is expected to answer a relevant clinical question or otherwise provide medical benefit to the patient.

超声和磁共振没有风险，妊娠患者可用。但应谨慎使用，只有在期望解答有关临床问题时或带来其他医疗获益时才使用。

With few exceptions, radiation exposure through radiography, computed tomography (CT) scan, or nuclear medicine imaging techniques is at a dose much lower than the exposure associated with fetal harm. If these techniques are necessary in addition to ultrasonography or MRI or are more readily available for the diagnosis in question, they should not be withheld from a pregnant patient.

除了少数例外，X线照相、CT扫描或核医学成像技术的辐射暴露剂量均远远小于引起胎儿伤害的暴露量。为了给妊娠患者诊断疾病，如果除了超声或磁共振之外这些检查仍属必要，或者更容易获得，则不应该被取消。

The use of gadolinium contrast with MRI should be limited; it may be used as a contrast agent in a pregnant woman only if it significantly improves diagnostic performance and is expected to improve fetal or maternal outcome.

钆增强磁共振应受到限制。只有在明显提高诊断能力并预期改善胎儿或母体结局的情况下，钆对比剂才能用于妊娠妇女。

Breastfeeding should not be interrupted after gadolinium administration.

使用钆对比剂后，母乳喂养不应中断。
