LoginObstetric ultrasound, also known as prenatal or pregnancy ultrasound, uses high-frequency sound waves to produce images of a developing embryo or fetus. Your doctor will use information from obstetric ultrasounds to track pregnancy progress, gestational age and help predict delivery dates. During an obstetric ultrasound, you will be on a bed, usually on your back. You may be asked to change position during your scan. Changing position helps move your organs and the fetus into a better position so the sonographer can capture high-quality images. If you have an Alberta Health Care card or valid health care card from out of province, there is no cost for an obstetric ultrasound except in Quebec. An obstetric ultrasound scan lasts approximately 45 to 60 minutes. If you have multiple fetuses, the exam will take longer, usually about 90 minutes. One significant other is welcome to join you in the room for the entire duration of the exam.
Back to Your pregnancy care. If you're pregnant in England you'll be offered an ultrasound scan at around 10 to 14 weeks of pregnancy. This is called the dating scan.
The scan is usually performed transabdominally but in a few cases it may be necessary to do the examination transvaginally. This is one of the most important scans during pregnancy and is recommended to all women. Each woman will be given an estimate of her individual chance of having a chromosomal condition present for this pregnancy. Parents will receive full counselling concerning the significance of these chances and the various options for further investigations including invasive testing or the NIPT. The nuchal translucency scan is a screening test which means that this test can only give a probability for a condition being present.
