There are two distinct measurements: the size of the nuchal translucency and the thickness of the nuchal fold. (wikipedia.org)
Nuchal fold thickness is measured towards the end of the second trimester. (wikipedia.org)
Screening for Down syndrome by a combination of maternal age and thickness of nuchal translucency in the fetus at 11-14 weeks of gestation was introduced in the 1990s. (wikipedia.org)
The scan is obtained with the fetus in sagittal section and a neutral position of the fetal head (neither hyperflexed nor extended, either of which can influence the nuchal translucency thickness). (wikipedia.org)
Background/aim: The aim of this study was to determine fetal nuchal translucency (NT) thickness nomogram values in first trimester in a Turkish population and compare them with previously reported European and Asian nomogram data. (tubitak.gov.tr)
Increased fetal nuchal translucency thickness at 10-14 weeks of gestation is a common phenotypic expression of fetal chromosomal defects, structural abnormalities and genetic syndromes. (nih.gov)
This study reports on the prevalence of structural abnormalities and genetic syndromes in 4116 chromosomally normal pregnancies with increased fetal nuchal translucency thickness and reviews the relevant literature. (nih.gov)
In fetuses with increased nuchal translucency thickness, the prevalence of major cardiac defects, diaphragmatic hernia, exomphalos, body stalk anomaly and fetal akinesia deformation sequence is substantially higher than expected in the general population. (nih.gov)
however, the number of affected cases, both in the present and in previous series of fetuses with increased nuchal translucency thickness, is too small for definite conclusions to be drawn. (nih.gov)
The rates of miscarriage and perinatal death increase, whereas the rate of survival and the prevalence of live births with no obvious abnormalities decrease with increasing nuchal translucency thickness. (nih.gov)
The measurements from this test, including the crown-rump length, fetal heart rate, and nuchal translucency thickness are combined with the age of the mother and certain other factors to determine the chance that the fetus may have a certain condition. (ssdev.ca)
Gestational age2
No significant association was found between serum cortisol and infants' birth weight for gestational age, head circumference, the sum of skinfold thickness, and crown-rump length. (bvsalud.org)
First, they check the gestational age of your baby by measuring your baby from top to bottom, recording the crown-rump-length (CRL). (ssdev.ca)
Fetus5
Normal thickness depends on the crown-rump length (CRL) of the fetus. (wikipedia.org)
The most accurate measurement for dating is the crown-rump length of the fetus, which can be done between 7 and 13 weeks of gestation. (wikipedia.org)

The crown-rump (C-R) length of the fetus is also illustrated. (medscape.com)
The fetus now measures between 13.4cm 15.2cm in length (crown to rump) and weighs approximately 200g. (thebirthcompany.co.uk)
Fetuses2
The incidence of NT thicknesses at fixed points of ≥ 2.5 mm, ≥ 3 mm, and ≥ 3.5 mm in normal fetuses were 6.7%, 4.1%, and 2.1%, respectively. (tubitak.gov.tr)
The fetuses were weighed and grouped according to their gestational ages which were estimated using their crown-vertebral-rump length. (animalscipublisher.com)
Measurement1
A measurement is then taken from the tip of the head to the little bottom, called the crown rump length (CRL). (dfmedical.ie)
Femur1
After 13 weeks of gestation, the fetal age may be estimated using the biparietal diameter (the transverse diameter of the head, across the two parietal bones), the head circumference, the length of the femur, the crown-heel length (head to heel), and other fetal parameters. (wikipedia.org)
Maternal1
Interpretation: Our results support the hypothesis that higher maternal cortisol levels may adversely impact birth weight, weight for length in newborns, and postpartum depressive symptoms in mothers. (bvsalud.org)
Pregnancy1
Is there a relationship between cord blood pregnancy-associated plasmaprotein-A and birth weight and length? (ntnu.edu.tw)
Width5
In all stages of development, the tongues were elongated, with flattened and rounded apex .At the first trimester, the tongues were almost uniform width and thickness throughout the length. (animalscipublisher.com)
These were sorted by Behle (1956) into Rocky Mountain, Great Basin, and California groups which differ in a complex mosaic involving tail length, bill length and thickness, flank color, back color, and eyebrow width. (sibleyguides.com)
The muzzle is moderately-short to medium long, wide, and tapers in width and thickness to a moderately pointed end at the nose. (duke.edu)
The relationship of body length to body depth and width equates to volume and capacity. (msstate.edu)

Heel1
Your growing baby now measures 28cm from crown to heel and weighs approximately 350g. (thebirthcompany.co.uk)
Normal1
Material and methods: Ultrasonographic measurements of crown-rump length (CRL) and NT thicknesses were obtained from 11 to 14 weeks of gestation in a normal Turkish population. (tubitak.gov.tr)
Long2
A goat should have a strong, level top and a long rump with a slight slope from hooks to pins. (msstate.edu)
but I let them laugh, so long as they did not go too far, when I would most assuredly have shown them, by the length of my Blade, not only what Regiment I belonged to, but what Mettle I was of. (gutenberg.org)
Baby2
Your baby now measures around 8cm, from crown to rump and weighs around 40g. (thebirthcompany.co.uk)
A Sonographer measures the baby by measuring from the crown to rump, also known as CRL or crown rump length. (peepingmomsultrasoundboutique.com)
Average2
The external fat thickness over the loin at the 13th rib should be between .08 to .12 inches or an average of .10 inch. (msstate.edu)
Goats will need to have an adequate length of cannon bone from knee to pastern and should be above average in overall length of body and general size. (msstate.edu)
Size1
The claw openings are set back from the free edge of the flippers by cartilaginous rods that extend the length of each digit, and expand the size of the flippers. (duke.edu)

Study1
Conclusion: The present study demonstrated the nomogram data of fetal NT thickness in a Turkish population. (tubitak.gov.tr)
Obvious1
The buff color is most obvious on the flanks and rump, but also suffuses the back. (sibleyguides.com)
Back1
This means the goat will achieve a greater percentage of his overall length down his top from the last rib back. (msstate.edu)

Both groups can show a solid black line extending from the crown down to the base of the bill, or a black and white speckled area there, or a solid white band continuing across the forehead. (sibleyguides.com)
