Keywords: Fetal, Fetus, Fetal growth restrictionAdipose tissue (AT, i.e., fat) deposition is reduced in undernourished growth-restricted fetuses (FGR) and may correlate with disease severity. Previous studies showed reduced AT using mainly linear sonographic measurements of the subcutaneous fat. We demonstrate the use of a two-point Dixon sequence for whole-body subcutaneous AT. The fat content of 64 fetuses (37 appropriate for gestation age [AGA], 18 FGR, and 9 small for gestational age) was measured using three adiposity parameters. We demonstrated third-trimester AT accretion in AGA fetuses and reduced AT in FGR. This study is the first to demonstrate whole-fetus subcutaneous AT changes in FGR.
