Anomaly Scan (18-24 Weeks)

  £180.00

An anomaly scan is known as a mid-pregnancy scan, 18-20 weeks (optimal suggestive time is 20-21 weeks). The main purpose of this scan is to entirely check your baby and make sure that the baby is developmentally and structurally normal.
This is very important to have this scan done as some babies’ health problems cannot be predicted by the health of parents or their family history.
At London Private Ultrasound, we offer a comprehensive Anomaly Scan of your baby, which is one of the two scans that are routinely offered to all pregnant women as part of antenatal care in the UK. This scan aims to perform a full survey of the baby’s structures, by assessing the baby’s growth by this stage of development, as well as many structures and organs. During this scan, the following would be examined: baby’s head and brain, baby’s face, spine, organs in baby’s abdominal cavity such as kidneys, stomach, bladder, diaphragm, bowel, abdominal wall, umbilical cord, baby’s spine, and limbs (arms, legs, hands, feet) and heart views.
The overall fluid around your baby would also be assessed alongside placental lie. This is to make sure the location of the placenta and to rule out that the placenta is not in the way of the birth canal.

If you wish to find out the gender of your baby we can offer a gender scan as a complimentary scan with the anomaly scan.

An anomaly Scan, also known as Mid-Pregnancy Scan or 20-Week Scan, is a detailed 2D ultrasound imaging, usually performed between 18 to 21 weeks of pregnancy. The purpose of this scan is to screen for 11 rare congenital conditions.
Anomaly Scan is routinely preformed between 18 - 21 weeks of pregnancy.
Prior to 18 weeks of pregnancy, your baby’s organs are not large enough to allow for a detailed scan.
It is not mandatory to have this scan. However, many parents opt for this scan to find out if their little one has a congenital disease.
During an Anomaly Scan, the sonographer will look for 11 congenital diseases affecting your baby’s brain, spinal cord, heat, face, kidney, bones and abdomen.
Some congenital defects are easier to identify than others. For instance, “Spina Bifida”, a condition affecting the baby’s spinal cord, can often be visualized clearly. Thus, Anomaly Scan can pick up 9 out of 10 cases of Spina Bifida. Opposingly, heart defects are more difficult to identify. Consequently, Anomaly Scan is only 50% accurate in detecting congenital heart conditions.
We can look for Down Syndrome during an Anomaly Scan. However, it is only 50 % accurate. First Trimester Screening, which includes Nuchal Translucency Scan and blood tests, is more sensitive to detect Down Syndrome (94 % accuracy). At Private London Ultrasound, we offer both the Anomaly Scan and First Trimester Screening.
Scans performed after the 22nd week of pregnancy may limit the possibility of an abortion according to local law.
In most cases, the Anomaly Scan shows a healthy baby as expected. However, if we suspect there might be something, you will be offered further tests to find out for sure.
This scan usually takes around 30 minutes. However, if your baby is not lying in a favourable position, we may ask you to take a walk and return, or have drink or some food, in order to encourage your little one to move a bit.
This scan is done transabdominally. So, it is recommended to have a full bladder.
