Babies with fetal growth restriction fail to grow properly in the womb and become hypoxic. They must be delivered prematurely to prevent stillbirth. DECIDE model fitting can determine properties which give information about the placental function and fetal blood saturation. This can be used to identify fetal growth restriction and manage the pregnancy effectively.

The aim is to compare DECIDE model fitting results for different mask segmentations. The placenta is segmented into lobules and used as a mask itself. Statistically significant differences of the fetal and placental properties between appropriately developing and growth-restricted pregnancies are determined.
