The death of 1 twin of monochorionic pairs is associated with a significant risk of brain hypoxic-ischemic damage in the survivor. Ultrasound may diagnose cerebral anomalies only a few weeks after the event. We report 3 cases of single survivors of monochorionic-twin pregnancies in which prenatal magnetic resonance imaging detected brain changes earlier and with better definition of the brain abnormalities than ultrasound.
单绒毛膜双胎妊娠中一个胎儿死亡与存活胎儿发生脑缺氧缺血性损伤的风险显著相关。超声可能在事件发生几周后才能诊断出脑异常。我们报告了3例单绒毛膜双胎妊娠的存活儿，其中产前磁共振成像比超声更早地检测到脑部变化，且对脑异常的定义更清晰。
