# Sonogram vs Ultrasound: The Shock You Never Saw Coming! When it comes to prenatal care and medical diagnostics, the terms “ultrasound” and “sonogram” are often used interchangeably—so much so that many expectant parents, and even some clinicians, assume they mean exactly the same thing. But while closely related, ultrasound and sonogram serve distinct roles in medicine—and understanding the difference can literally change the “shock” you receive during your pregnancy. ### What Is an Ultrasound? An ultrasound is a diagnostic imaging technique that uses high-frequency sound waves (typically 2–10 MHz) to create real-time images of internal body structures. In pregnancy, this means visualizing the fetus, placenta, uterine lining, and amniotic fluid. Physicians use ultrasound to monitor fetal growth, detect abnormalities, check heart activity, and assess overall pregnancy health.
