Pregnancy Ultrasound

We provide rapid access to diagnostic tests for women with complications of early pregnancy (generally between 5 & 12 weeks of pregnancy). Bleeding or pain in early pregnancy is not uncommon and may provoke a great deal of anxiety. The nature of these problems is that they occur without warning. Hence we will always aim to see people the same day either in Harley St or Parkside Hospital in Wimbledon.

Nuchal Scan

The vast majority of babies are born normal. However, all women have a small risk of delivering a baby with a physical handicap. One cause can be a chromosomal abnormality such as Down’s syndrome. The risk of a fetus having such an abnormality can be assessed on the basis of maternal age, a scan and a blood test. You and your partner can then decide if the risk of a fetus having a chromosomal abnormality warrants having an invasive test such as CVS or amniocentesis.

Harmony Test

Non-invasive prenatal testing (NIPT) analyses cell-free DNA circulating in the pregnant mother’s blood. It is a new option in prenatal screening for Down syndrome (trisomy 21) and other common fetal chromosomal conditions (trisomies 18 and 13).

The test involves taking a sample of maternal blood and is safe and non invasive with a high detection rate for the following 4 chromosomal abnormalities

  • Down’s Syndrome – 99%
  • Edwards Syndrome – 98%
  • Patau’s Syndrome – 80%
  • Turners Syndrome – 96%

NIPT can be undertaken from 10 weeks of pregnancy alongside a dating scan to accurately confirm gestation and the result will be available after 14 days

Invasive Tests

These invasive tests examine the chromosomes of the baby. The most common reason they are performed is to exclude Down’s syndrome, but many other chromosome abnormalities can also be excluded. The principal concern for any women undergoing these tests is the risk of miscarriage. This is approximately 1% for both of the following procedures.

Fetal Anomaly Scan

A detailed examination is performed of the baby from top to toe to exclude any chromosome abnormality or structural defect.

Fetal Growth Scan & Assessment

These scans are performed between 24 and 42 weeks. More than one scan may be required. The aim is to check the growth and health of the baby. This is carried out by:

  • Measuring the baby’s head, abdomen and thigh bone
  • Assessing the amount of amniotic fluid surrounding the baby
  • Recording the presence of fetal movements
  • Noting the appearance and position of the placenta
  • Measuring the blood flow in the umbilical cord and fetal vessels using
    Doppler Ultrasound

3D and 4D Ultrasound Scans 

3D scan

This scan provides you with a three dimensional image of your baby. The best time to perform the scan is between 25-29 weeks of pregnancy. The health your baby is of primary concern and we will always begin the scan by assessing the baby’s growth. Sometimes the baby is not in a favourable position to perform the scan, in this case we may ask you to go for a walk or drink some water.

We will record some cine clips of the scan and still images on a CD/DVD to take away with you. Bookings and enquiries can be made via our Harley Street office.
