Routine obstetric sonography, commonly known as prenatal ultrasound, is a standard medical imaging procedure performed during pregnancy to monitor the development and health of the fetus. Using high-frequency sound waves, a transducer is placed on the abdomen or inserted into the vagina to create images of the uterus, placenta, and fetus. This imaging technique provides valuable information about the baby's growth, position, and anatomy, helping healthcare providers assess for any potential abnormalities or complications. Routine obstetric sonography plays a crucial role in determining the due date, identifying multiple pregnancies, checking for fetal well-being, and diagnosing conditions such as congenital anomalies or placental issues, contributing to the optimal management and care of both the mother and the unborn child throughout pregnancy.
