“…In the PTB sub-analysis, the MRI-EFW and US-EFW comparator was derived from the ABW; however, charts to calculate birthweight centiles are based on different populations to the fetal growth charts and also takes into account fetal sex [52,53]. Weight at birth is likely to be physiologically larger to weight in utero due to the mode of delivery, whereby cesarean newborns typically weigh more than standard vaginal deliveries, and the use of intravenous fluids during labor has been seen to artificially increase newborn weight as a result of this intervention [54][55][56]. These factors were not controlled for in this study, although clinically appropriate newborn and fetal growth charts and use of centiles helped to standardize the comparisons.…”

Objectives: The aim of this study was to compare the standard ultrasound (US) estimated fetal weight (EFW) and MRI volume-derived methods for the midtrimester fetus. Methods: Twenty-five paired US and MRI scans had the EFW calculated (gestational age [GA] range = 20–26 weeks). The intra- and interobserver variability of each method was assessed (2 operators/modality). A small sub-analysis was performed on 5 fetuses who were delivered preterm (mean GA 29 +3 weeks) and compared to the actual birthweight. Results: Two MRI volumetry EFW formulae under-measured compared to US by −10.9% and −14.5% in the midpregnancy fetus (p < 0.001) but had excellent intra- and interobserver agreement (intraclass correlation coefficient = 0.998 and 0.993). In the preterm fetus, the mean relative difference (MRD) between the MRI volume-derived EFW (MRI-EFW) and actual expected birthweight (at the scan GA) was −13.7% (−159.0 g, 95% CI: −341.7 to 23.7 g) and −17.1% (−204.6 g, 95% CI: −380.4 to −28.8 g), for the 2 MRI formulae. The MRD was smaller for US at 5.3% (69.8 g, 95% CI: −34.3 to 173.9). Conclusions: MRI-EFW results should be interpreted with caution in midpregnancy. Despite excellent observer agreement with MRI volumetry, refinement of the EFW formula is needed in the second trimester, for the small and for the GA and preterm fetus to compensate for lower fetal densities.

“…MRI can monitor fetal growth through volumetric measurements, which have been shown to be superior to US estimated fetal weight. 35 , 36 The excellent soft-tissue contrast provided by MRI also allows for the measurement of organ growth, including liver, kidneys, brain, lungs, heart, and placenta. 37 The assessment of differential organ growth is useful for identifying altered growth distributions such as asymmetric FGR.…”

Observing fetal development in utero is vital to further the understanding of later-life diseases. Magnetic resonance imaging (MRI) offers a tool for obtaining a wealth of information about fetal growth, development, and programming not previously available using other methods. This review provides an overview of MRI techniques used to investigate the metabolic and cardiovascular consequences of the developmental origins of health and disease (DOHaD) hypothesis. These methods add to the understanding of the developing fetus by examining fetal growth and organ development, adipose tissue and body composition, fetal oximetry, placental microstructure, diffusion, perfusion, flow, and metabolism. MRI assessment of fetal growth, organ development, metabolism, and the amount of fetal adipose tissue could give early indicators of abnormal fetal development. Noninvasive fetal oximetry can accurately measure placental and fetal oxygenation, which improves current knowledge on placental function. Additionally, measuring deficiencies in the placenta’s transport of nutrients and oxygen is critical for optimizing treatment. Overall, the detailed structural and functional information provided by MRI is valuable in guiding future investigations of DOHaD.
