The incidence of abdominal and pelvic cancer in pregnancy is low, but it is rising as the population of pregnant women gets older. Depending on disease stage, gestational age and patient's preference, active surveillance as well as surgery and chemotherapy are feasible options during pregnancy. Correct diagnosis and staging of the tumor is crucial for choosing the best therapeutic approach. Moreover, a reproducible modality to assess the treatment response is requested. Magnetic resonance imaging (MRI) is commonly used with good results for the local staging and treatment response evaluation of most abdominal and pelvic cancers in nonpregnant patients, and it is considered relatively safe during pregnancy. The purpose of this article is to analyze the most relevant topics regarding the use of MRI in pregnant women with abdominal and pelvic cancer. We discuss MRI safety during pregnancy, including the use of gadolinium-based contrast agents (GBCAs), how to prepare the patient for the exam and MRI technique. This will be followed by a brief review on the most common malignancies diagnosed during pregnancy and their MRI appearance.
妊娠期腹盆部癌症的发病率较低，但随着孕妇年龄的增长呈上升趋势。根据疾病分期、妊娠周数和患者意愿，妊娠期可行密切监测、手术和化疗。正确诊断和分期肿瘤对于选择最佳治疗方法至关重要。此外，还需要一种可重复的方法来评估治疗反应。磁共振成像（MRI）常用于非妊娠患者大多数腹盆部癌症的局部分期和治疗反应评估，其结果良好，并且在妊娠期间被认为相对安全。本文旨在分析 MRI 在妊娠腹盆部癌症患者中的应用的最相关问题。我们讨论了妊娠期 MRI 的安全性，包括钆基对比剂（GBCA）的使用、如何为检查和 MRI 技术准备患者。然后简要回顾一下妊娠期最常见的恶性肿瘤及其 MRI 表现。
