Gastrointestinal malignancies, though uncommon in pregnancy, present several unique challenges with regards to diagnosis, staging, and treatment. Imaging the pregnant patient with a suspected or confirmed GI malignancy requires modifications to the radiologic modality of choice and protocol in order to minimize harm to the fetus, ensure accuracy in diagnosis and staging and guide treatment decisions. In this review article, we discuss the imaging approach to the pregnant patient with GI cancer, including safe radiologic modalities and modifications to imaging protocols. We also review the most common GI cancers encountered in pregnancy, including colorectal, pancreatic, gastric, and small bowel tumors, with emphasis to imaging findings, staging, and treatment considerations.
胃肠道恶性肿瘤在孕期虽不常见，但在诊断、分期及治疗方面存在一些独特挑战。对疑似或确诊患有胃肠道恶性肿瘤的孕妇进行成像检查时，需要对所选的放射学检查方式及方案进行调整，以尽量减少对胎儿的损害，确保诊断和分期的准确性并指导治疗决策。在这篇综述文章中，我们讨论了针对患有胃肠道癌症的孕妇的成像方法，包括安全的放射学检查方式及成像方案的调整。我们还回顾了孕期最常见的胃肠道癌症，包括结直肠癌、胰腺癌、胃癌和小肠肿瘤，重点介绍了成像结果、分期及治疗考量。
