Ultrasound for your peace of mind

At OMNI Ultrasound & Gynaecological Care in Sydney we offer a number of ultrasounds to assess the health and well-being of your unborn child

Whether you are newly pregnant or late in the 3rd trimester, we can provide you with the ultrasound scan to best suit you and your baby’s needs. From being able to assess how far along you are to the health and well-being of your unborn child, OMNI uses only the latest ultrasound technology.

How far along are you?

The gestational age of your baby is different from the fertilisation age of an embryo or fetus. The fertilisation age is counted from fertilisation whereas the gestational age is greater by around two weeks and determined by the date of your last menstrual period (LMP). It is important to know the gestational age of your baby because it provides valuable information for your Obstetrician such as:

  • Potential or expected problems
  • Directly affects the medical treatment plan for the baby

An ultrasound for women during early pregnancy can alter the timing of your delivery because it is more accurate than the LMP.

Location of your pregnancy

Pregnancies of unknown location (PULs) make up about 10% of early pregnancy scans. However, a PUL does not mean that you have an ectopic pregnancy.  The best way to diagnose whether or not you have an ectopic pregnancy is to have a high quality transvaginal ultrasound (TVS) performed by one of our experienced sonographers at OMNI. TVS is the best non-invasive way to ascertain if you have an ectopic pregnancy.

An ectopic pregnancy is, as a rule, not a normal developing pregnancy and in most instances does not have an embryo.

The health and well-being of your unborn baby

To ascertain the health and well-being of your unborn baby we offer a number of scans:

1.       Fetal morphology

Between 18 and 20 weeks a detailed ultrasound is carried out. This scan examines the anatomy of your baby from head to toe to exclude any physical abnormalities. While this scan is normally carried out between 18 – 20 weeks is not a problem to perform it up to 22 weeks gestation. This scan can also tell you the gender of your baby should you wish to know.

Results of the morphology scan will be sent to your referring GP or Obstetrician the same day

2.       Fetal growth

Between 24 – 42 weeks a fetal growth scan is carried out to assess the growth as we well as the well-being of your child; this ultrasound takes around 20 minutes to perform.

At the fetal growth scan we look at and assess a number of areas including:

  • Measuring your baby’s head, abdomen and thigh bone in order to estimate the fetal weight
  • Observing the baby’s activity
  • Recording the position of the placenta
  • Assessing the amount of amniotic fluid around the baby
  • Measuring the blood flow in the umbilical cord using Doppler ultrasound


Results of the fetal growth scan will be sent to your referring Obstetrician or GP. If the team at OMNI are concerned about the findings of this scan we will contact your doctor the day of the scan.

3.       3D/4D ultrasound

This scan is best performed around 26 – 32 weeks of your pregnancy.

An ultrasonography allows OMNI’s sonographers to evaluate your unborn fetus and for visualisation of your baby in-utero. A 3D ultrasound is done through your abdomen and there is no risk to your baby or to you.

4D ultrasound is similar to 3D except that the images received are in real time instead of being delayed. While this scan is best performed around 26 – 32 weeks, it can be carried out at the time of either your morphology or growth scan.

OMNI Ultrasound & Gynaecological Care

Condous performs Advanced Endosurgery procedures for women needing intervention for pelvic masses, adnexal pathology, severe endometriosis or hysterectomy. He also runs ‘Hands on’ Live Sheep Laparoscopic Workshops for gynaecologists at Camden Veterinarian School.
Having completed an undergraduate degree with the University of Adelaide, he left Australia in 1993 and moved to London where he completed his training in Obstetrics and Gynaecology. From 2001 to 2003 Condous worked as a Senior Research Fellow at St George’s Hospital, London. At St George’s he set up the Acute Gynaecology Unit, the first in the United Kingdom. It was also during this time that he developed an interest in Early Pregnancy and especially the management of pregnancies of unknown location (PULs). Condous has developed many mathematical models for the prediction of outcome of PULs which have been featured in numerous peer review journals. In 2005, he returned to Australia where he completed his Laparoscopic Fellowship at the Centre for Advanced Reproductive Endosurgery, Royal North Shore, Sydney.

Condous was appointed as a Consultant Gynaecologist and Senior Lecturer at Nepean Hospital in 2006 and soon was made Associate Professor. In 2010, he was made Departmental Head of Obstetrics and Gynaecology at Nepean Hospital. He obtained the MRCOG in 1999 and was made FRANZCOG in 2005. In 2009, he was awarded his Doctorate in Medicine (MD), University of London, for his thesis entitled: “The management of pregnancies of unknown location and the development of new mathematical models to predict outcome”.

Condous has edited three books including the “Handbook of Early Pregnancy Care”, published over 100 papers in international journals and is internationally renowned for his work in Early Pregnancy. He is the Associate Editor for Gynaecologic Obstetric Investigation, which is a European based journal, as well as the Australasian Journal of Ultrasound in Medicine (AJUM). He is on the organising committee and is an invited speaker at the International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG) Scientific meeting in Sydney 2013. His current research interests relate to the management of ectopic pregnancy, 1st trimester growth, PULs and miscarriage and the use of transvaginal ultrasound (in particular sonovaginography, to predict posterior compartment deep infiltrating rectovaginal endometriosis).Condous is also actively involved with post-graduate education including the annual running of the Early Pregnancy and Gynaecological Ultrasound Interactive Courses for Sonologists, Radiologists, Sonographers and Gynaecologists in Australia.
