Nhs dating scan
The first is known as the ‘dating scan’ because it helps to show how many weeks pregnant you are, it can also check your baby's development.Additionally you may be offered a special ultrasound called a ‘nuchal translucency scan’ (NT) which in combination with a blood test is used to screen for Down’s syndrome.The second is at around 20 weeks into your pregnancy.The scans are offered as medical examinations and form part of a screening programme but we understand that the ultrasound scan allows you that first precious glimpse of your new baby.
Pregnancy and the fetal heart can be seen from six weeks gestation by vaginal scan and from eight to nine weeks by abdominal scan.
Accurate measurements and images are taken of the gestational sac and the 'crown to rump' length of the embryo, to accurately date the pregnancy.
Serum blood screening in early pregnancy is performed alongside nuchal scanning in order to identify high-risk pregnancies.
