Assessing Placental Oxygenation using MRI in Women Reporting Reduced Fetal Movements

 

Objective

To compare T2*-weighted MRI assessment of placental

oxygenation in late gestation pregnant women with and without

reduced fetal movements (RFMs), in different maternal positions

and presence of painless uterine contractions.

Background

• Perception of RFMs has been associated with risk of FGR, SGA,

placental insufficiency and stillbirth

• The majority of women with perceived RFMs go on to have a

healthy pregnancy

• The incidence of RFMs is 22%

• 43% of women are induced, 11% have a planned caesarean birth

• There is no current method to predict birth outcomes with RFMs
