including biparietal diameter (BPD), femoral length (FL), abdominal circumference (AC) and estimated fetal weight (EFW) was done.
Ultrasonography (US) in the 1st, or early 2nd trimester, is highly reproducible and widely used for dating, since early biological variability of fetal biometry is minimal.
The following were excluded: twins (n= 17), prenatally detected fetal anomaly (n=9), early pregnancy loss (n=18), asymmetric fetal biometry on 1st US (n=5), later confirmed as not pregnant (n=13), and dating information not available (n=30) or insufficient (n=66).
Our results (57% of deliveries within 7 days and 85% within 14 days; 95% CI -11-21) were in keeping with other studies that used dating formulae based on early or mid-gestation US, [1,9,11,14,19] in line with the limited biological variability in early fetal biometry and reports of better dating with 1st trimester US.
2) Clinical benefit in diagnosis, treatment planning, and family counseling has been reported for evaluation of facial abnormalities, neural tube defects, skeletal defects, congenital heart disease and the central nervous system1 as well as fetal biometry.
total lung and fetal body volumes) and enhanced fetal biometry analyses (e.
The 3-dimensional SSFP sequence is valuable in this regard to manipulate 1 sequence and swiftly depict gross anatomy (Figure 1, 13B) and pathology, as well as quantify fetal biometry.
Whether they are evaluating the fetal heart in real time or analyzing fetal biometry
to assess growth and well-being, it's essential for the clinician to be able to view high quality, clear ultrasound images," said senior vice president, Ultrasound, for Philips Healthcare Anne LeGrand.
Information derived from the ultrasound examination included fetal biometry
and NT measurement.
The ultrasound evaluations assessed calvaria shape, a four-chamber view of the heart, outflow tracts, three-vessel cord, hands, feet, cisterna magna size, fetal biometry
, and amniotic fluid volume.

On ultrasound scanning, she had a single live intrauterine fetus with cephalic presentation of 32 [+ or -] 3 weeks by fetal biometry
