What stage do I have an anomaly pregnancy scan?

We perform the Anomaly pregnancy scan from 20 weeks up to 24 weeks of pregnancy.

How should I prepare for an anomaly pregnancy ultrasound?

When you attend for an anomaly pregnancy ultrasound you do not need a filled urinary bladder to help view the pregnancy. You will need to know your established due date. It is important to wear loose comfortable clothing.

Why is an anomaly scan performed?

The anomaly scan essentially examines the baby’s anatomy in a detailed manner and is carried out between 20 and 24 gestational weeks. Measurements & all your baby’s organs will be checked by the Sonographer while capturing images as well. They will check your baby's spine, face, the baby's abdominal wall, stomach, kidneys, and heart. Your baby’s hands, arms, legs, and feet will also be checked. The Sonographer will also take measurements of your baby’s abdominal circumference, femur, and head circumference. The Sonographer will also check the umbilical cord, amniotic fluid around the baby & the placenta.

Will I be able to see the scan?

Yes, the ultrasound is available for you to view on a large screen located at the end of the ultrasound couch. The sonographer will explain what you are looking at and point out various items to look at on the ultrasound. You will also be able to hear the baby’s heartbeat. We aim to make this ultrasound scan an enjoyable experience for you.

What to expect at Ultrasound Dimensions?

When you arrive at Ultrasound Dimensions you will be met by our receptionist. You will then be asked to complete a waiver, even if you have been here before. You can then relax in our waiting area until the sonographer comes to meet you and take you to the scanning room. Your personal details from your completed waiver will be confirmed by the sonographer before beginning the scan.

What happens during the anomaly pregnancy ultrasound scan?

The anomaly scan also known as the twenty-week scan is a non-invasive, trans-abdominal scan (on the stomach area), and you don’t have to attend with a full bladder for this scan. An abdominal scan is performed by placing some gel and the transducer onto the abdomen of the patient.

Will I be able to find out the gender of my baby?

At 18 weeks or later we can determine the gender of your baby. However, sometimes, the baby is not in a desirable position to tell the gender. If you want to determine the gender of your baby, please let us know on your registration form and confirm with the sonographer at the start of your scan. Determining the gender of your baby depends on baby to be in a position that can allow the Sonographer to view the genital area and sometimes the baby may not oblige!

What happens if a problem is suggested?

During your scan, if a problem is suggested, you will be notified by the sonographer that there may be a concern and advised to contact your obstetrician to discuss our findings in more detail. We will provide details of our findings for you and you are welcome to contact us for further clarification at any stage.

Do I need a doctor's referral for a pregnancy ultrasound?

Pregnancy scans at our centre are elective so you don't have to have a referral. Just call or email to make an appointment.

Can family members attend my ultrasound appointment?

A pregnancy scan is a family affair at our clinic, so you can share your baby scan experience by bringing whomever you want and as many people as you like.
