Overview

Watching your baby grow.

Obstetric ultrasound uses sound waves to look at your baby during pregnancy. Like all ultrasound, it's safe and non-invasive, and it doesn't use ionising radiation.

What we can see changes as your pregnancy goes on. Here's what's happening at each stage.

Through your pregnancy

Three trimesters, three different views.

  • (01)Up to 13 weeks

    First trimester

    Up to 13 weeks, your baby grows to as much as 7.5 cm long. The eyes, toes, joints and nerves are developing, along with the circulatory and digestive systems.

  • (02)Rapid development

    Second trimester

    The skeletal, digestive, circulatory and nervous systems develop rapidly, and your baby grows up to 33 cm long. In the second trimester, 3D/4D ultrasound can help with the anatomical survey and the detection of any abnormalities.

  • (03)Growth & position

    Third trimester

    Organs and nerves continue to develop fully, rapid weight gain begins, and most babies move into the head-down position for birth. 4D ultrasound is useful in the third trimester for looking at your baby's movement and biophysical profile.

Preparation

Get ready for your pregnancy scan.

Early pregnancy scans need a full bladder, so timing your water matters. For later scans we'll let you know about any preparation when you book.

Choose your scan

Full bladder

First-trimester pregnancy

Your bladder needs to be full for an early pregnancy scan.

  1. 01

    1½ hrs before

    Empty your bladder.

  2. 02

    Next 30 min

    Drink 1 litre of water over the next half hour.

  3. 03

  1. (01)

    We'll give you any preparation instructions when you book your appointment.

On the day

What happens on the day.

  1. Step 1: Before you come

    If you're in your first trimester, follow the full-bladder steps. Bring your referral and your Medicare card, and wear loose, comfortable clothing.

  2. Step 2: Your scan

    Your sonographer moves a small hand-held probe over your abdomen with a little gel to look at your baby.

  3. Step 3: Your results

    Your doctor can view your images online within minutes, and once our radiologist has reported, the results go straight to them. Book a follow-up with your doctor to talk through what they mean.

Good to know

Your questions,
answered.

  • (01)Can I go to the toilet before a first-trimester scan?

    Please don't. Empty your bladder 1½ hours before your appointment, drink 1 litre of water over the next half hour, finish drinking 1 hour before your appointment time, then hold on until your scan.

  • (02)Do I need to prepare for a later pregnancy scan?

    We'll let you know about any preparation when you book your appointment.

  • (03)Can I see my baby in 3D or 4D?

    Yes. As well as pregnancy scans requested by your doctor, we offer elective 3D/4D baby scans. No referral is needed, and the best images usually come between 24 and 34 weeks.

  • (04)Which clinics offer pregnancy scans?

    Ultrasound imaging is available at all our sites: Pakenham, Officer, Cranbourne, Traralgon, Rosebud and Koo Wee Rup.

  • (05)Is my pregnancy scan bulk billed?

    Some ultrasounds are not bulk billed. Our team will let you know about any cost when you book.
