Antenatal Sonography
Antenatal sonography, commonly known as prenatal ultrasound, is a crucial imaging technique used in central diagnostics during pregnancy. It is a non-invasive and safe procedure that utilizes high-frequency sound waves to create real-time images of the developing fetus and maternal structures. Antenatal sonography plays a pivotal role in monitoring fetal health, assessing growth, and detecting potential anomalies, providing valuable information for healthcare providers to ensure a healthy pregnancy and plan appropriate care. This article explores the significance, applications, and benefits of antenatal sonography in central diagnostics.

By visualizing the fetal anatomy and identifying any potential issues, antenatal sonography aids in early detection and timely intervention for congenital abnormalities and other pregnancy-related complications.
Types of Antenatal Sonography
Transabdominal Ultrasound: The most common type of antenatal sonography, transabdominal ultrasound, is performed by placing a specialized transducer on the pregnant woman’s abdomen. It produces images of the fetus, placenta, and amniotic fluid, providing information about fetal development and overall well-being.
Transvaginal Ultrasound: In certain cases, transvaginal ultrasound may be recommended during early pregnancy to obtain more detailed images of the fetus. This technique involves inserting a small probe into the vagina to get closer to the pelvic organs and provide higher-resolution images.
Applications of Antenatal Sonography
Dating and Viability: During the first trimester, antenatal sonography is used to determine the gestational age of the fetus accurately. It also confirms the viability of the pregnancy by detecting fetal heartbeats.
Fetal Anatomy Survey: Typically performed between 18 to 22 weeks of pregnancy, the fetal anatomy survey is a comprehensive evaluation of the fetus’s anatomy. It assesses the brain, heart, spine, limbs, and internal organs, helping identify any structural abnormalities.
Growth and Well-being: Antenatal sonography is used throughout the pregnancy to monitor fetal growth and ensure the baby’s well-being. Serial measurements of the fetus’s size and weight provide valuable information about the baby’s development.
Multiple Gestations: In pregnancies with multiple fetuses (twins, triplets, etc.), antenatal sonography is essential for monitoring the development and well-being of each individual fetus.
Benefits of Antenatal Sonography
Early Detection: Antenatal sonography allows for early detection of congenital anomalies and pregnancy-related complications, facilitating timely interventions and treatment plans.
Reassurance and Bonding: Seeing the developing fetus during antenatal sonography can provide reassurance and enhance the emotional connection between the expectant parents and their baby.
Non-Invasive and Safe: Antenatal sonography is a non-invasive procedure that does not involve radiation, making it safe for both the pregnant woman and the developing fetus.
Informed Decision-Making: The information obtained from antenatal sonography empowers healthcare providers to make informed decisions regarding the management of pregnancy and potential interventions.
