Abstract：
Monochorionic twins are at risk for complications due to the presence of placental vascular anastomoses, including twin-twin transfusion syndrome, twin anemia-polycythemia sequence, selective fetal growth restriction, and twin reversed arterial perfusion sequence. While ultrasound is the primary modality to screen for the development of these complications, MRI plays an important role in assessing monochorionic twin pregnancies for the development of other complications, such as neurologic injury. In this article, the authors review the ultrasound imaging findings associated with monochorionic twin complications, management options, and the role for MRI in these pregnancies.
摘要：
由于胎盘血管吻合的存在，单绒毛膜双胞胎有并发症的风险，包括双胎输血综合征,双胎贫血-红细胞增多症序列,选择性胎儿生长受限,和双反向动脉灌注序列。虽然超声是筛查这些并发症发展的主要方式，MRI在评估单绒毛膜双胎妊娠其他并发症的发展中起着重要作用。比如神经损伤。在这篇文章中,作者回顾了与单绒毛膜双胞胎并发症相关的超声成像结果，管理选项，以及MRI在这些怀孕中的作用。
