You will have heard about ultrasound before, but may have some questions about ultrasound and your baby. Ultrasound uses high frequency sound waves to see internal structures of the body. A hand held ‘transducer’ sends a brief pulse of sound into the body. When this sound reaches an internal structure it sends back an echo. These echoes are seen as the images on the monitor of the ultrasound machine. Diagnostic ultrasound has been used for over 80 years in pregnancy. Ultrasound is considered safe, and there is no known side effects.

The NT scan measures the clear translucent space in the tissue at the back of your baby’s neck. This is the “nuchal translucency. Some practitioners also look for the presence of the fetal nasal bone during the NT scan. If no nasal bone is seen in the developing baby, some experts believe this increases the likelihood of chromosomal abnormalities.

There are many reasons for having an ultrasound at this stage, but one of the most common is to screen for one of the congenital chromosomal abnormalities — Trisomy 21, otherwise known as Down Syndrome. This means that there is an extra chromosome — 21 contained in every cell of the body. People with Down Syndrome have physical and intellectual disabilities. Older women are more at risk of having a baby with Down Syndrome.
When a woman is around 12 weeks pregnant her risk of having a baby with Down Syndrome can be fairly accurately assessed. First trimester screening for Down Syndrome can be done with a blood test between 10 weeks and 13 weeks and 6 days. When a foetus has Down syndrome they tend to have more fluid at the base of their neck, in the region known as the nuchal fold area. This fluid can be measured in a test called nuchal translucency. This can be measured in an ultrasound done between 11 weeks and 13 weeks and 6 days.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures. Dating scans are usually recommended if there is doubt about the validity of the last menstrual period.
By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures. Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation.
This is because the fetus is growing so quickly that there is a big difference in size from week to week. However, the accuracy of the ultrasound examination is always dependent on the skill of the sonographer and the quality of the equipment.
