What Is a Dating Ultrasound?
A dating ultrasound, also known as a pregnancy ultrasound or an early ultrasound, is a medical procedure that uses sound waves to create images of a developing fetus in the womb. It is commonly performed during the first trimester of pregnancy to determine the gestational age and estimated due date of the baby. This ultrasound is non-invasive and considered safe for both the mother and the baby.
During a dating ultrasound, a trained technician or sonographer will apply a gel to the mother’s abdomen and use a transducer, which emits sound waves, to capture images of the uterus and the developing baby. These images are then analyzed by a radiologist or obstetrician to determine the gestational age and assess the baby’s health.
