Explore the Difference Between 2D 3D and 4D ultrasound

Serving the Greater St. Louis area

2D Ultrasound is the traditional black-and-white imaging most parents are familiar with. It shows a cross-sectional view of your baby–great for measuring growth, checking anatomy and internal organs to monitor development. Clinically, it's the gold standard for diagnostic accuracy in the clinical setting.

What is 2D Ultrasound?

Adds depth and detail, capturing still images of your baby’s surface features–like the curve of a cheek or the shape of a tiny nose. It’s especially popular for offering a more lifelike glimpse of your little one with higher resolution than 4D due to the static image.

What is 3D ultrasound?

4D ultrasound shows your baby in 3D but live and in motion. With 4D you are seeing your baby in real time when it yawns and stretches. It can offer amazing insight into your baby’s features and what they are going to look like before birth.

Upon booking any of our sessions we will always try our best to obtain 3D & 4D images for you; however it is important to note that image quality is dependent on multiple factors such as fetal position, body composition, and gestational age.

An Advanced Practice Sonographer or MFM sonographer often working in Maternal Fetal Medicine (MFM), is a highly trained ultrasound specialist who focuses on high-risk pregnancies and complex fetal evaluations. Unlike general sonographers, MFM sonographers have advanced certifications and clinical experience in areas like fetal anatomy, growth assessment, and fetal echocardiography. They work closely with perinatologists (high-risk OBs) to monitor babies with special medical needs, perform detailed diagnostic scans, and support families through critical milestones.

In everyday terms: they’re the ones trusted to look closely, catch what others might miss, and provide reassurance when it matters most. Their training blends deep technical skill with compassionate care—making them uniquely equipped to guide families through both joyful and challenging moments in pregnancy.

What is an “advanced practice Sonographer” or MFM Sonographer?

TWO! Ideally, 1st trimester (8 weeks) to confirm the due date and another during the 2nd trimester (20 weeks) for an anatomy scan. Additional ultrasounds beyond these two are performed when clinically necessary or at the discretion of the OBGYN. 
(Example: Some clinicians prefer to do a growth scan closer to delivery to confirm head position and obtain measurements for an overall size).

What is an “advanced practice Sonographer” or MFM Sonographer?

Your OB/GYN is your primary pregnancy provider. If complications arise, they refer you to an MFM. The MFM physician completes an additional 2 to 3 years of high risk training to support prenatal surveillance and decision-making. It is a collaboration to optimize outcomes for mother and baby when risks are elevated.

NO. The 10 or 30 min window is for the time scanning starts to the time it stops. It does not include the time it takes to set up or pack up at the end. The set up time takes roughly 10-15min depending on parking and the same to break down.

What is an “advanced practice Sonographer” or MFM Sonographer?

“Hello Bambino” and “The Meet Cute” are virtually the same package but The Meet Cute allows more flexibility for our clinicians outside of regular working hours. We are making evenings and weekends available for a 30 minute scan or gender reveal party and even open to traveling outside of our normal areas. Pricing may vary depending on distance but we want to serve as many people as possible. If you do not live in the Saint Louis area that is okay! We recommend reaching out via email in advance so we can get in contact with you to arrange a visit.

No. Images are deleted once we provide you with a USB to keep indefinitely. With this you can store them or print them however you wish after the visit. We understand everyone loves the office prints however that kind of photo paper will continue to develop over time and will not provide clients with long term memorabelia.
