Us obstetric nuchal dating scan best online dating sites for new york
The ability to diagnose physical abnormalities depends on the equipment used, the position of the foetus, the stage of the pregnancy and the experience of the person performing the ultrasound.
If a physical abnormality is identified, it may suggest the presence of a birth defect and/or hereditary condition.
Transvaginal scans usually provide clearer pictures during early pregnancy and in obese women.
Also used is Doppler sonography which detects the heartbeat of the fetus.
Hi Ladies, My letter for my first scan next wee ( I will be 13 weeks) says 'US Obstetric nuchal dating scan'. I soooooooo can't wait as this will be my first scan and want a little relief that all looks well !!!
Is this a combined nuchal and dating scan, a little confused... Thanks Cx Hi Sounds like it is the NT scan and dating - they are usually done together and they will probably do your blood work at the same time. Usually takes about 15 minutes, they'll check all is well - arms, legs, brain shape, profile, heart, bladder and kidney function etc and then measure the fluid behind baby's neck. I think including blood tests we were in and out within 40 minutes.
is an ultrasound of your pelvis which produces an image of the foetus in the uterus. An image of the baby is produced by the reflection of those sound waves.
The images (sonogram) are displayed on a television screen.
Performing an ultrasound at this early stage of pregnancy can more accurately confirm the timing of the pregnancy and can also assess for multiple fetuses and major congenital abnormalities at an earlier stage.
In normal state, each body tissue type, such as liver, spleen or kidney, has a unique echogenicity.
Fortunately, gestational sac, yolk sac and embryo are surrounded by hyperechoic (brighter) body tissues.
Doppler sonography can be used to evaluate the pulsations in the fetal heart and bloods vessels for signs of abnormalities.
A gestational sac can be reliably seen on transvaginal ultrasound by 5 weeks' gestational age (approximately 3 weeks after ovulation).
