Ultrasound of Obstetric - Ultrasound Images Gallery
This radiation-free, non-invasive prenatal imaging test uses high-frequency sound waves to generate detailed 3D images of pregnancy-related structures, including the uterus, developing fetus, and placenta. Unlike standard 2D ultrasounds, this exam captures volumetric, lifelike images that allow your care team to assess fetal development, placental position, and urogenital health with greater detail, with no special preparation, contrast agents, or radiation exposure needed.
This 30-minute, non-invasive 3D obstetric ultrasound uses sound waves to create detailed three-dimensional images of the uterus, fetus, and placenta with no radiation, contrast, or special preparation required.

What Is a 3D Obstetric Ultrasound?
This specialized prenatal imaging exam uses high-frequency sound waves (not ionizing radiation) to create detailed three-dimensional, volumetric images of the structures involved in pregnancy, including the uterus, developing fetus, and placenta. Unlike standard 2D ultrasounds that produce flat cross-sectional images, 3D ultrasound captures thousands of individual sound wave reflections from multiple angles to build a lifelike, rotatable model of these structures, giving your care team a more comprehensive view of fetal anatomy, placental location, and uterine health.
Clinical Applications for Urogenital System Evaluation
This exam is used to evaluate a wide range of urogenital and pregnancy-related clinical concerns, including confirming fetal growth and development milestones, identifying structural fetal anomalies, assessing placental position to rule out complications like placenta previa or placental abruption, evaluating the uterine wall for abnormalities such as fibroids, congenital uterine defects, or uterine scarring, and monitoring multiple gestations (twins, triplets, or higher order multiples). It is also frequently used to provide detailed, lifelike images for parental bonding, and to support diagnostic planning if a concern is identified on a standard 2D prenatal ultrasound.
What to Expect During Your Exam
The exam takes approximately 30 minutes to complete, requires no special preparation (such as a full bladder, unless your provider gives you specific instructions), and carries no risk of radiation exposure or claustrophobia, as no enclosed scanning equipment is used. A trained sonographer will apply a water-based, hypoallergenic gel to your lower abdomen to help the transducer glide smoothly over your skin and capture clear sound wave data; you may feel slight, mild pressure from the handheld transducer as it moves across your abdomen, but the exam is completely painless, and you will be able to view real-time 3D images of your pregnancy on a screen during the scan.
