In preeclampsia, the erythropoetin level in the fetus has been reported to be moderately elevated and the number of erythroid cells in the fetal liver reduced. Assessment of fetal liver health and function over gestation, including hepatic hematopoiesis, is of great interest. T2* relaxometry is an emerging quantitative biomarker of liver iron content. In this study, we assessed fetal liver T2* in the midtrimester pregnancy. A fetal liver T2* of 22ms and 25ms at 14 and 20 weeks of gestation, respectively, was observed at 1.5T. T2* values are significantly correlated with gestational age but not with obesity or mothers’ age.
