Summary

This study was designed to see if a special MRI technique could measure blood flow in the placenta during pregnancy. The goal was to compare placentas in pregnancies where the baby is growing poorly (IUGR) with healthy pregnancies. However, the study was withdrawn before any participants were enrolled, so no results are available.
