20 Week Scan

Expectant parents are provided with the opportunity to undergo a comprehensive ultrasound examination known as the 20-week scan, or the anomaly scan. This milestone appointment, typically scheduled around the midpoint of pregnancy, serves as a check-up to assess the health and development of the growing baby. In this blog post, we will delve into the details of the 20-week scan, its purpose, the information it provides, and its significance in ensuring a healthy pregnancy and birth.



Importance of the 20-Week Scan

The 20-week scan offers a detailed evaluation of the baby's anatomy and overall well-being. This ultrasound examination allows healthcare professionals to assess the baby's growth, detect any potential abnormalities or developmental concerns, and provide guidance and support to parents accordingly. It provides a crucial opportunity to identify any conditions that may require further investigation, specialised care, or planning for the baby's birth.


What to Expect during the 20-Week Scan

The 20-week scan is a non-invasive procedure performed by a qualified sonographer or healthcare professional. It usually takes place in a hospital or clinic setting, where state-of-the-art ultrasound equipment is available. In Warwickshire, scans are usually offered at Warwick Hospital, Stratford-Upon-Avon Hospital, or University Hospital Coventry. During the scan, the sonographer applies a gel to the mother's abdomen, which helps transmit sound waves and obtain clear images of the baby.


The sonographer will then move a handheld device called a transducer gently across the abdomen, capturing images of the baby from various angles. These images are displayed on a monitor, allowing both the sonographer and the parents to observe and discuss the findings together. The sonographer may take measurements, check the baby's organs, limbs, spine, head, and heart, and assess the placenta and the amniotic fluid levels.


Information Provided by the 20-Week Scan

The 20-week scan aims to provide a comprehensive overview of the baby's development and identify any potential anomalies or abnormalities. Some of the key aspects evaluated during this scan include:


1. Baby's Growth and Position: The scan helps determine the baby's size and position within the womb, ensuring optimal growth and assessing the placental location.


2. Organs and Body Structures: The sonographer examines the baby's organs, including the brain, heart, kidneys, spine, and limbs, to detect any signs of structural anomalies.


3. Placental Function: The scan evaluates the position and function of the placenta to ensure it is providing adequate nourishment to the baby.


4. Amniotic Fluid Levels: The level of amniotic fluid surrounding the baby is assessed to ensure it is within the normal range, as abnormal levels may indicate underlying issues.


5. Gender Identification: If desired, the sonographer can often reveal the baby's gender during the 20-week scan, although this is not the primary purpose of the examination and the sonographer may refuse to do this. If this is the case and you would like to know the gender of your baby then we would suggest a private scan.


Managing Findings and Follow-up


In some cases, the 20-week scan may identify potential concerns or anomalies. It is important to note that not all abnormalities are necessarily serious or life-threatening, and further tests or consultations may be required to confirm the findings and discuss potential management options. The healthcare team will guide parents through any necessary steps, which may include additional scans, consultations with fetal medicine specialists, or genetic counseling.


Emotional Aspect and Bonding Opportunity

Beyond the medical aspects, the 20-week scan provides an invaluable emotional experience for expectant parents. Seeing clear images of their baby, witnessing their movements, and hearing their heartbeat can enhance the bonding process and help parents develop a deeper connection with their unborn child. It also allows parents to share the joy of the pregnancy with family and friends, further strengthening their support network.



The 20-week scan is a milestone in the journey of pregnancy, offering reassurance and valuable insights into the well-being and development of the baby. With its comprehensive examination of the baby's anatomy and organs, this scan helps healthcare professionals identify potential concerns and provide guidance to parents.
