“…In human preterm infants, whole-body protein metabolic rates are also higher when compared with infants born at term (36). However, human fetal liver volume as a percentage of body weight does not decrease as much throughout gestation as it does in fetal sheep (37).…”

Background: Despite nutritional intervention, albumin concentrations are often low in critically ill premature neonates. Objective: Our aim was to quantify albumin synthesis rates during early life under physiologic circumstances. Human fetuses thereby reflect the developmentally related optimal condition. Design: Pregnant women undergoing elective cesarean delivery received 3 different labeled amino acid infusions starting at different times before surgery. With the use of mass spectrometry techniques, this novel model enabled us to quantify fetal albumin synthesis from a single blood sample taken from the umbilical cord after cesarean delivery. The fractional synthesis rate reflects the fraction of the albumin pool that is daily renewed. The absolute synthesis rate is the absolute amount of albumin that is daily synthesized. Results are expressed as medians (25th-75th percentile). Conclusions:On a weight basis, albumin synthesis rates in premature fetuses were higher than in fetuses at term and were higher than the rates previously found in neonates after preterm birth. Considering that the premature fetal liver can synthesize albumin at a high rate, the observed hypoalbuminemia in premature infants therefore seems to suggest that current (nutritional) therapies fail to meet requirements necessary to sustain optimum albumin synthesis rates.

“…53 The reproducibility of fetal liver volume recordings and tracings has been shown to be quite accurate with a total coefficient of variation of less than 4%. 54 In uncomplicated pregnancy, fetal liver volume demonstrates a 10-fold increase with advancing gestational age (Fig. 8) and increasing fetal weight.…”

“…85 Normal mean umbilical venous blood flow ranges between 33 ml/min at 20 weeks and 220 ml/min at 36 weeks, which is a sevenfold increase. 54 When calculated per kilogram fetus as shown in Fig. 14, there is a significant decrease in normal volume blood flow from 117.5 Ϯ 33.6 ml/min at 20 weeks to 78.3 Ϯ 12.4 ml/min at 36 weeks of gestation.…”

“…[63][64][65] After upper abdominal circumference, the best prediction of fetal growth restriction is the hepatic volume. 66 Therefore, hepatic volume may become a new useful parameter in the assessment of fetal growth. For many years fetal weight calculation has been mainly based upon abdominal circumference measurement.…”

Three-dimensional, multiplanar sonography, using a volume data set acquired with a 3D probe, has revolutionized ultrasonographic imaging and takes sonographers to a new perception of the fetus in 3 dimensions. Real time scanning, until the late nineties only possible in B-mode, can now be performed in 3D with up to 40 frames/sec. Fetal neurology emerged as a new perinatal research field with the 4D visualization of fetal behavior. Doppler ultrasound, diversified and refined from continuous wave and pulsed Doppler to Color – and Power Doppler, when added to 3D sonography, creates fascinating options of noninvasive fetal vascular mapping (sonoangiography) and vascular assessment of placenta. The diagnostic and demonstrative potential of an acquired 3D volume data set can be maxed with the help of postprocessing and rendering software. After storage, the evaluation of fetal 3D data sets can happen without the patient, with the option of specialist consultation, using telemedicine. In the article, the new 3D “modes” like surface rendering, maximum mode, 3D Color and Power Doppler, STIC, volume rendering, and glass body rendering, are described and illustrated in their display of normal fetal anatomy.
