Best 3D/4D Ultrasound in Knoxville

Keepsake ultrasound studios that offer 3D/4D imaging, gender reveals, and HD Live scans between 14–34 weeks. Not a replacement for diagnostic OB scans.

How we rank

◆Sonographer credentials & training
◆Equipment (HD Live / 5D vs. older 3D)
◆Session length and image count
◆Google review volume and average
◆Family-friendly experience & privacy

We weight equipment (HD Live vs. standard 3D), sonographer experience, session length, family-friendly setup, and Google review depth (not just star average — volume matters). Studios without a dedicated private suite, or that only offer standard 3D, are ranked below those with HD Live and true experience-oriented setups. Diagnostic capability is intentionally not part of the rubric — that's your OB's job.

Frequently asked questions

When is the best time to get a 3D/4D ultrasound?

Weeks 26–32. Facial features are defined but there's still room for baby to reposition. After 33 weeks, imaging becomes hit-or-miss regardless of studio.

What's the difference between 3D, 4D, and HD Live (5D)?

3D is a still surface reconstruction; 4D is 3D in motion (real-time). HD Live (marketed as 5D) adds a virtual light source for photographic depth and lifelike facial detail. HD Live is the current top tier.

Is a keepsake ultrasound safe?

Ultrasound has been used in obstetrics for over 50 years without documented harm at diagnostic energy levels. Reputable studios use the same equipment settings as diagnostic labs.

Does insurance cover elective ultrasound?

No. Elective/keepsake scans are not medical care and are not covered by any insurance in Tennessee, including TennCare. Expect to pay $70–$350 out of pocket.
