Bringing a new life into the world is a miraculous journey, and modern medicine has provided us with incredible tools to witness and monitor this process. One such invaluable tool is the ultrasound scan, a window into the womb that allows healthcare professionals to ensure the well-being of both the mother and the developing fetus According to Dr. Archit Singhal, MBBS, MD (Radiodiagnosis), Fellowship in Fetal Medicine, Consultant - Fetal Medicine Specialist, Motherhood Hospitals, Noida, Peoples often asked about the significance of ultrasound scans during pregnancy. In this blog, we will unravel the mysteries surrounding the timing and purpose of these scans.

The Timing of Ultrasound Scans:

Ultrasound scans are a routine part of prenatal care, and their timing is strategic, providing crucial insights at different stages of pregnancy. The American College of Obstetricians and Gynecologists (ACOG) recommends the following schedule for ultrasound scans:

First Trimester (6-13 weeks):

Dating Scan: This initial scan helps determine the gestational age, estimated due date, and the number of fetuses.

Nuchal Translucency (NT) Scan: Conducted between 11 and 14 weeks, this scan assesses the risk of chromosomal abnormalities.

Second Trimester (18-22 weeks):

Anatomy Scan: Also known as the mid-pregnancy scan, it provides a detailed look at the baby's anatomy, ensuring normal development.

Gender Identification: For parents who wish to know, this is often the time when the baby's gender can be determined.

Third Trimester (28-32 weeks or as needed):

Growth Scan: Monitors the baby's growth and checks the amniotic fluid levels.

Position Scan: Determines the baby's position in preparation for delivery.

The Why Behind Ultrasound Scans:

Monitoring Fetal Development:

Ultrasound scans allow us to closely monitor the baby's growth, ensuring that the fetus is developing at the expected rate.

Detecting Abnormalities:

Early ultrasounds, especially the NT scan and anatomy scan, help identify potential chromosomal abnormalities or structural defects in the fetus.

Ensuring Placental Health:

Scans help assess the health and position of the placenta, vital for the baby's nourishment.

Guiding Medical Interventions:

In cases of high-risk pregnancies or complications, ultrasound scans provide essential information to guide medical interventions and treatment plans.

Preparing for Delivery:

The position scan in the third trimester helps healthcare providers determine the best mode of delivery and anticipate any potential challenges.

Bonding and Reassurance:

Beyond medical necessity, ultrasound scans offer an emotional connection for parents, providing glimpses of their growing baby and fostering a sense of reassurance.


Ultrasound scans during pregnancy are not just routine procedures; they are windows into the intricate process of fetal development. These scans empower healthcare professionals to ensure the health and well-being of both the mother and the unborn child. As we continue to unlock the mysteries of pregnancy, ultrasound technology stands as a beacon, guiding us through this miraculous journey.
