biometry until 22 weeks of gestation. There is no uniform dating policy when both a valid last menstrual period and ultrasonographic dates are available in determining the date of confinement. When both methods are compared, there are obvious advantages of routine scanning in the first half of ...

Ultrasound confirmation of gestational age Since the 1970s ultrasound scans have allowed measurement of the size of developing embryos directly and so allow for an estimation of gestation age. Ultrasound dating is most accurate if undertaken in the first trimester (first 12 weeks of pregnancy) with...
Consequently, fetal ultrasound late in pregnancy has a wide margin of error of at least ±2 weeks’ gestation. Here, we utilise state-of-the-art machine learning methods to estimate gestational age using only image analysis of standard ultrasound planes, without any measurement information. The ...
Serum albumin was also determined. The resultant bilirubin titration curve was analyzed using the least squares fit of the empiric equation Y = aXb and calculation of the association constants (Ka) using Scatchard plots.DorohyA RrJohnD KnnyNaturePediatric Research...
Finally, amniotic fluid reference ranges in MCDA twins differ from those in singletons. After 28 weeks' gestation, measurements of the DVP were smaller in monochorionic twins. As monochorionic twins are more often small for gestational age than are dichorionic twins and singletons, and growth...
Two of them were pregnant within four months and were delivered by caesarean section at 38 weeks of gestation. The main interest of this technique is to avoid a laparotomy; thus, reducing the abdominal wall aggression and the recovery time. 展开 关键词:...
The analysis of secular trends for birthweight and gestational age in twins was based on 32,379 twin livebirths (1967–95). Taking into account the observed secular trends in birthweight for 35–40 weeks of gestation, data on twins born during 1987–95 only were included in the calculation...
An extensive ensemble of 25 voxel models has been used to investigate the effects of body posture, anatomy, age and pregnancy. This set includes six adult models, eight child models and seven pregnant female models at various stages of gestation. The four postures investigated in the HPA adult...
