Ultrasounds & scans
How 2D, 3D and 4D ultrasounds work, when to book them and how to get the clearest picture of your baby.
13 Week Sonogram and 12 Week Scan: What You Will See
What the end-of-first-trimester scan checks, what a 12 or 13 week sonogram picture really shows, how to prepare, and why it can't tell you everything yet.
20 Week Ultrasound: What the Anatomy Scan Shows
What the 20 week anatomy scan checks, what 20 week ultrasound pictures can show (profile, hands, feet, maybe the sex), how to prepare and what it can't tell you.
3D Ultrasound: What It Shows, When to Book and Is It Safe
How a 3D ultrasound builds your baby's face from echoes, what it can and can't show, the weeks that work best, and what the FDA, ACOG and AIUM say about keepsake scans.
3D Ultrasound vs Real Baby: Why They Look Different
Why your newborn looks different from the 3D scan: fat gained after the scan, fluid and pressure on the face, how the image is rendered and the first days after birth.
3D vs 4D Ultrasound: Differences, Timing and Which to Pick
3D vs 4D ultrasound explained: a 3D scan is a still image, 4D is the same image in motion. A side-by-side table with 2D, 5D/HD Live and 8K, plus timing.
4D Ultrasound: What You See in a Live Baby Scan
A 4D ultrasound is a 3D scan in motion. What babies actually do on screen, why faces hide behind hands and placenta, what you take home and what experts say.
8K Ultrasound: What It Really Is and How Accurate It Is
An 8K ultrasound is an AI rendering of a 3D scan, not a sharper scan. What it shows, what a 2025 review found about accuracy, and how to judge one.
Best Time to Get a 3D Ultrasound: A Week-by-Week Guide
Why a 3D face looks bony at 20 weeks and round by 28: what each week from 16 to 34 shows, the usual keepsake window, and what the FDA and AIUM advise.
Hair on a 3D Ultrasound: Can You Really See It?
Scalp hair sometimes shows on a late 2D scan as fine bright lines, but rarely on a 3D picture. What you can see, what you can't, and what decides newborn hair.
How to Get Clear 3D Ultrasound Pictures
What makes a 3D ultrasound picture clear: timing, the baby's position, fluid and the placenta. A sourced prep checklist, when to rebook, and printout tips.
How to Read an Ultrasound Picture: Labels, Numbers and Shapes
Read your ultrasound picture in three passes: the shades, the orientation and the text band. A table explains GA, CRL, BPD, HC, AC, FL, EFW, EDD and more.
Are 3D Ultrasounds Safe? What the FDA and Doctors Say
No study shows diagnostic ultrasound harms babies, yet the FDA, ACOG and AIUM discourage keepsake-only scans. Their positions, plus questions to ask a studio.
Sonogram vs Ultrasound: Is There a Difference?
Sonogram and ultrasound mean almost the same thing: ultrasound is the test, a sonogram is the picture it makes. Plus every other term on your scan paperwork.
Ultrasound Pictures by Week: What Your Baby Looks Like
What your ultrasound pictures show at 6–8, 12, 16, 20 and 28+ weeks: the 8-week bean, the 12-week profile, the anatomy scan and the third-trimester face.
