The placenta is essential for fetal development but its in vivo study, including the study of placental perfusion is still very limited to date. MRI is a safe examination that offers new perspectives for the study of placental function that is altered in many conditions (IUGR, preeclampsia…) and placental anatomy (placenta accreta…). The different MRI sequences (DCE, IVIM, BOLD, ASL…) are new tools that may soon allow us to assess precisely placental function and anatomy, in vivo and non-invasively.
胎盘对胎儿发育至关重要，但迄今为止，其体内研究，包括胎盘灌注研究仍然非常有限。磁共振成像（MRI）是一种安全的检查方法，为研究在许多情况下（胎儿生长受限、先兆子痫等）发生改变的胎盘功能以及胎盘解剖结构（胎盘植入等）提供了新的视角。不同的MRI序列（动态对比增强、体素内不相干运动、血氧水平依赖性功能磁共振成像、动脉自旋标记等）是新的工具，可能很快使我们能够在体内且无创地精确评估胎盘功能和解剖结构。
