Although this is usually fairly accurate, it can not be taken as a guarantee of sex as ultrasound is not 100% accurate.
This scan is the most significant one undertaken during pregnancy, because it can reassure the parents that everything appears to be as it should be.
The nuchal translucency is a measurement of an area of fluid behind the baby’s neck.
Ultrasound imaging in pregnancy is widely used to evaluate the baby.
It can determine if a baby is present, the position of the fetus and if there is a multiple pregnancy.
The position of BMUS on the use of ultrasound to produce “keepsake” images of the fetus is outlined in the European Committee of Medical Ultrasound Safety (ECMUS) statement, endorsed by BMUS. Ultrasound scans should not be performed solely for producing souvenir images or recordings of a fetus or embryo. The production of souvenir images or recordings for the parents to keep is reasonable if they are produced during a diagnostic scan, provided that this does not require the ultrasound exposure to be greater in time or magnitude (as indicated by the displayed MI and TI) than that necessary to produce the required diagnostic information. Attention is drawn to the recommendation of the EFSUMB Clinical Safety Statement for Diagnostic Ultrasound that ultrasound examinations should be performed only by competent personnel who are trained and updated in ultrasound safety matters.
The nuchal scan (NT scan) is a screening done during an antenatal ultrasound to measure the amount of fluid at the base of your baby's neck.
The scan can confirm the number of babies in the uterus, the embryo can be observed and measured by about five and a half weeks and a heartbeat usually detected by 6 weeks.
Scans at this stage in pregnancy are reassuring for women experiencing bleeding, pain or who have had previous miscarriages.
Transvaginal scanning may also be used to obtain a better image of the womb.
Nuchal translucency scan This is a scan which is usually carried out at 11-13 weeks and is a method of screening for chromosomal abnormalities without having an invasive test such as an amniocentesis.
For all Obstetrics scans, no special preparation is needed, although it is best to wear loose clothing that can easily be lifted or removed in order to expose your abdomen.
You will lie on your back on an examination couch and the transducer moved back and forth across your stomach in order to gain the best possible image of the fetus.
Souvenir Scanning Developments in real-time 3D and 4D ultrasonic imaging have led to parents asking for souvenir (keepsake) video recordings of the fetus, sometimes at several stages during the pregnancy.Tags: Adult Dating, affair dating, sex dating
