Computed tomography (CT) is performed with increasing frequency on pregnant women. Although exposure to a single abdominal CT does not appear to increase the risk of spontaneous abortion or congenital malformations, it is thought to double the risk of childhood cancer. This article provides a general overview of radiation risks to fetuses, what patients and health care workers know and believe about these risks, how CT is currently being used in the care of pregnant patients, and how the risks associated with this use can be managed. The goal of this overview is to stimulate discussion among health care providers in diagnostic imaging, to help them deal with their patients' concerns, and to help them come to terms with their own concerns when they are called on to perform CT on pregnant women.
计算机断层扫描（CT）在孕妇中的使用频率日益增加。尽管单次腹部CT照射似乎不会增加自然流产或先天性畸形的风险，但据认为会使儿童患癌风险加倍。本文概述了胎儿面临的辐射风险、患者和医护人员对这些风险的了解与认知、CT目前在孕妇护理中的使用情况，以及如何管理与此使用相关的风险。本概述的目的是激发诊断成像领域医护人员之间的讨论，帮助他们应对患者的担忧，并在被要求为孕妇进行CT检查时，帮助他们正视自己的担忧。
