Medical imaging during pregnancy may be necessary to diagnose conditions that affect the outcome of the mother and fetus. Diagnosis and staging of cancer in pregnant women can be particularly challenging due to fear of inherent risk to the fetus, lack of standardized imaging protocols, and ethical challenges posed while choosing the best imaging option. Ultrasound and MRI, due to lack of ionizing radiation, are preferred over CT and nuclear imaging. The latter may be considered only if the benefits of imaging outweigh maternal and fetal risk without exceeding the cumulative established fetal radiation dose threshold. This article provides an overview of all currently available imaging options that can be used for imaging cancer during pregnancy to support the best possible maternal and fetal outcomes.
医学影像学在妊娠期间可能是必要的,以诊断影响母亲和胎儿结局的疾病。由于对胎儿固有风险的恐惧、缺乏标准化的成像方案以及在选择最佳成像方法时面临的伦理挑战,对孕妇进行癌症的诊断和分期可能特别具有挑战性。由于缺乏电离辐射,超声和 MRI 优于 CT 和核成像。只有在不超过累积确定的胎儿辐射剂量阈值的情况下,当成像的益处超过母婴风险时,才可以考虑后者。本文概述了所有目前可用于妊娠期间癌症成像的成像选择,以支持尽可能好的母婴结局。
