Is Ultrasound Safe During Pregnancy?

If you're expecting, it's completely natural to wonder whether repeated ultrasound scans are safe for your baby. It's one of the most common questions we hear at the clinic — and the short answer is yes.

Why ultrasound is considered safe

Diagnostic ultrasound has been used in pregnancy care for decades and, unlike X-rays or CT scans, does not use ionising radiation. It works using sound waves, and major medical bodies worldwide continue to recommend it as the standard, safe way to monitor a pregnancy.

That said, safety in practice also comes down to how a scan is performed — using the minimum scan time needed to get clear, useful images, and only scanning as often as medically appropriate rather than for repeated non-medical reasons.

How many scans will I need?

Most straightforward pregnancies involve a handful of key scans across the three trimesters — an early dating scan, an NT scan around 11–13 weeks, a detailed anomaly scan around 18–22 weeks, and growth/Doppler checks later on. Your doctor will guide you on the right schedule based on your specific pregnancy.

If you have any concerns about an upcoming scan, the best step is simply to ask — we're always happy to explain what a scan involves and why it's being recommended before you come in.
