[Placental MRI: physiology and pathology]

Abstract

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.
