Fetal growth retardation (FGR) is a serious condition affecting babies in utero that can be identified by means of a placental phenotype related to structural and functional changes in the placenta. Magnetic resonance imaging (MRI) measured the relaxation times T1 and T2 as possible biomarkers of this condition and placentas were collected for the histological verification of FGR pathology. We show for the first time that both in utero T1 and T2 demonstrate a significant negative correlation with the gestational age at 1.5 T and that relaxation times correlate with histological biomarkers of placental development.
