Overview of fetal growth scan

Fetal growth and doppler scan are done on the final trimester of pregnancy to determine the wellness and growth of the baby inside the mother’s womb. The fetal growth ultrasound at 32nd week determines the essential part of maternity care which is directly associated with perinatal morbidity and stillbirth. The guidelines provide a clear pathway between the third trimester and the delivery date.

The first fetal scan is suggested in between 28 weeks to 32 weeks so that preventive medical intervention improvises the outcomes for the babies.  Growth and doppler scan use soundwaves to detect the movement of blood vessels. It studies the blood circulation in the baby, uterus, and placentae. It is indeed a valuable screening tool that aids in assessing unwanted interventions and their adverse effects. Routine fetal growth scan and doppler ultrasound of blood vessels in the placentae and uterus of pregnant women is an accurate way of improving the outcomes of both child and mother. 

As babies grow weekly, growth scans with doppler tests are performed accordingly to keep a substantial track of the baby's growth. A mother who has previously faced pregnancy complications or has medical issues (high blood pressure or diabetes) or is expecting twins can take up the growth scan and doppler test to figure out the abnormalities caused by fetal growth restrictions. 

Why fetal growth ultrasound in the third trimester?

The fetal growth ultrasound examination in the third trimester is useful for several reasons. It allows to:

  • Observe the fetal heartbeat.
  • Figure out the position and presentation of fetal.
  • Identify the growth and size of fetal.
  • Examine the volume of amniotic fluid around the baby.
  • See the position of the placenta.
  • Check the flow of blood through the umbilical cord to the baby. 
  • Examine the activities and baby movement.
  • Measure the length of the cervix.
  • Check the position of uterine fibroids. 

All these measurements allow assessing the baby’s growth and well-being. It also permits to generate an estimated fetal weight and height during the obstetric fetal growth scan. The measurement charts are filled with exact figures to assess the average growth rate on their stages. The fetal measurements taken for a growth scan consists of:

  • Abdominal Circumference (AC), an analysis of the abdomen area.
  • Head Circumference (HC), an analysis of the head area.
  • Femur Length (FL), an analysis of thigh bone area.
  • Biparietal diameter (BPD), an analysis of the head area.

Serial growth scans pregnancy for abnormalities while the doppler ultrasound looks for significant fetal abnormalities that are performed in between the 10 to 20 weeks gestation. 

The process involved in fetal growth and well-being scan.

The obstetric fetal growth scan gets performed by placing an ultrasound transducer on the abdomen. The object is moved around with the aid of slippery gel. Unlike a regular ultra-sound, the bladder does not need to be full. Instead, it should be in between full and empty. The entire antenatal growth scan takes up a total time of 20-30 minutes. At the end of the examination, a transvaginal scan is performed in an empty bladder to get a better result of the lower edge placenta and to measure the exact length of the cervix. Therefore, ultrasound growth scan accuracy and is recommended by the obstetrician for a fetal growth ultrasound on the third trimester of pregnancy. 

At Vatsalya, our obstetric service includes antenatal growth scans (before birth). Throughout the pregnancy period, our team of doctors makes sure the baby and mother are healthy. We also assist the patients in testing any encountered abnormalities and teach the mothers to manage the discomforts of pregnancy.
