Clinical Trial Summary

The purpose of this study is to test the application of newly generated magnetic resonance imaging (MRI) protocols for the assessment of placental perfusion in human subjects. The primary objective is to validate and establish the utility of placental MRI in pregnant women. The study will be entirely MRI-technology based with collection of placental tissue at the time of infant delivery for later correlative studies.


Clinical Trial Description

The placenta provides all the nutrition from a pregnant mother to a developing fetus. A placenta that functions normally is needed to ensure normal fetal growth and development. Unfortunately, the placenta is the least understood human organ even though it is involved in all pregnancy complications. The placenta is so poorly understood because our current methods to look at it during pregnancy, like ultrasound, do not provide enough information about placental growth and function.

This study will help provide information about:

- How the placenta grows and develops during pregnancy

- How the placenta delivers nutrients, like oxygen to the developing fetus

- If placental function using new advanced imaging tools can predict pregnancy complications like fetal growth restriction, stillbirth, preeclampsia and preterm labor

This study will explore how blood flow to the placenta affects placental growth, fetal growth, and oxygen delivery to the fetus. Blood flow to the placenta may determine how the placenta supports fetal growth and development. Having a way to measure placental function during pregnancy may provide a way to understand normal pregnancies but importantly also identify pregnancies at increased risk for pregnancy complications.

Additionally we want to have an ancillary intrauterine growth restriction (IUGR) arm; the objective of this ancillary study is to test the sensitivity of the placental MRI protocol in women with confirmed cases of IUGR in the third trimester. ;
