Congratulations, you’re expecting! Pregnancy is an exciting and beautiful journey, filled with wonder and anticipation. One of the first important steps in this journey is getting early pregnancy scans. These scans play a vital role in monitoring the health and development of your baby, providing crucial information about their growth and ensuring the wellbeing of both mother and child. In this article, we will delve into the different types of early pregnancy scans, their significance, and what you can expect during each scan.

  1. Early Pregnancy Scans: A Brief Overview

Early pregnancy scans are medical procedures that use ultrasound technology to create images of the developing fetus in the womb. They are typically performed during the first trimester of pregnancy, usually between 6 to 14 weeks. These scans help healthcare professionals assess the viability of the pregnancy, check for any abnormalities, determine gestational age, and monitor the overall health of the mother and the baby.

  1. Transabdominal Ultrasound

The transabdominal ultrasound is one of the most common types of early pregnancy scans. During this scan, a gel is applied to the mother’s abdomen, and a transducer is used to emit sound waves that create images of the baby on a monitor. This non-invasive procedure allows healthcare professionals to check the baby’s heartbeat, verify the number of fetuses, assess the gestational sac, and determine the estimated due date. It is a painless and safe procedure that provides crucial information about the early stages of pregnancy.

  1. Transvaginal Ultrasound

In certain situations, a transvaginal ultrasound may be recommended. This type of scan involves inserting a probe into the vagina, which allows for closer and clearer visualization of the developing fetus. Transvaginal ultrasounds are often conducted during the early stages of pregnancy when a transabdominal scan may not provide sufficient details. They are particularly useful in detecting ectopic pregnancies, ruling out miscarriages, and assessing fetal well-being. Rest assured, this procedure is considered safe and generally discomfort-free.

  1. Dating Scan

The dating scan, also known as the viability scan, is usually the first early pregnancy scan you will undergo. This scan aims to accurately determine the gestational age of the fetus and estimate the due date. It also helps identify any potential issues or abnormalities that may affect the pregnancy. During the dating scan, healthcare professionals measure the length of the fetus from crown to rump, check the heartbeat, and assess the general health of the baby. It is an essential scan that sets the foundation for monitoring the pregnancy’s progress.

  1. Nuchal Translucency Scan

Around the 11th to 14th week of pregnancy, you may be offered a nuchal translucency (NT) scan. This specialized scan measures the thickness of fluid at the back of the baby’s neck and assesses the risk of chromosomal abnormalities, particularly Down syndrome. The NT scan, in combination with maternal blood tests, helps determine the likelihood of such conditions and provides information for informed decision-making. It is an optional but highly recommended scan that offers valuable insights into your baby’s health.

  1. Anomaly Scan

The anomaly scan, also known as the mid-pregnancy or 20-week scan, is a detailed examination of the baby’s anatomy. This scan allows healthcare professionals to thoroughly evaluate the baby’s development and identify any potential anomalies or structural issues. It also provides an opportunity for parents to see their baby’s growth and movements. During the anomaly scan, specific measurements are taken, such as head circumference, abdominal circumference, and limb length. The scan can bring great peace of mind by confirming that the baby is developing normally.


Early pregnancy scans are invaluable in monitoring the health and progress of both mother and baby during the beautiful journey of pregnancy. The transabdominal and transvaginal ultrasounds, along with dating scans, nuchal translucency scans, and anomaly scans, provide crucial information about the developing fetus, assess potential risks, and offer peace of mind to expecting parents. Understanding the different types of early pregnancy scans empowers parents to actively participate in their prenatal care and make informed decisions for the wellbeing of their baby.
