3D-4D Pregnancy Ultrasound

Ultrasound provides useful information about the uterus, ovaries and baby that enables appropriate antenatal care. Fetal size and heart rate are checked at all stages of pregnancy, as well as the maternal uterus, ovaries and cervix.

  • WHAT IS PREGNANCY ULTRASOUND

    Ultrasound provides useful information about the uterus, ovaries and baby that enables appropriate antenatal care. Fetal size and heart rate are checked at all stages of pregnancy, as well as the maternal uterus, ovaries and cervix. Pregnancy ultrasound is a non-invasive painless examination to assess fetal growth, position and anatomy, and placental site, as well as the maternal uterus and ovaries. Ultrasound can detect many, but not all abnormalities. Demonstrating a fetal abnormality on ultrasound depends on many factors, including fetal age and position at the time of the ultrasound, and the size and type of abnormality.

    There is very little preparation required for these exams. You should have some fluid in the bladder, and it is recommended to wear clothing that allows easy access to the entire abdominal region. Medicare provides a rebate for ultrasound during the first and second trimester, and when there is a clinical concern.

  • Before Your Ultrasound

    Your bladder must be full at the time of your appointment.  Empty your bladder (1) hour before your appointment, then drink one (1) litre of clear fluid or cordial.  Do not empty your bladder before your appointment unless really necessaryl

    If you have had to fill your bladder for an ultrasound, please advise our reception staff if you are feeling too uncomfortable, or feel you may have to empty your bladder very soon. While we make every attempt to avoid delays, occasionally we might have to make allowances for urgent cases and this could cause unintended delays for other patients and appointments.

    The sonographer may ask you to change into a gown to avoid spoiling your clothes with gel. Once you are safely positioned on the ultrasound couch, the sonographer will dim the lights for better viewing. Special gel is used between the transducer and your skin, to enable optimal transmission of the sound waves. The transducer is moved over the area of interest. You may be asked to roll onto your side or take a deep breath to optimise the images. If you experience any pain during the scan because of your position or the pressure of the transducer, you should advise the sonographer.

  • FIRST TRIMESTER ULTRASOUND - NUCHAL TRANSLUCENCY SCAN

    During the first trimester an ultrasound can determine the gestational age, if the patient doesn’t know her last menstrual period (LMP).  The First Trimester Screen (FTS) and Nuchal Translucency Scan is performed between 12 weeks and 14 weeks to test for any chromosomal abnormalities. This scan does not directly diagnose an abnormality, but predicts the likelihood of one being present, and can suggest further investigation.

    If the patient has had symptoms such as bleeding or pain during the first trimester, an ultrasound can determine whether the pregnancy is in the correct position within the uterus, or whether there has been a miscarriage.

    Medicare will provide a rebate for one or more scans during this period if certain clinical criteria are met.

  • SECOND TRIMESTER ULTRASOUND - MORPHOLOGY SCAN

    During the second trimester, a Morphology Scan (18-22 weeks) is used to check fetal growth, numerous important organs such as the spine, heart, brain and kidneys, placental site, and amniotic fluid volume. During the morphology scan, the sonographer will check for signs of a possible genetic problem. All Australian women are encouraged to have a morphology scan, and Medicare will provide a rebate for one or more scans during this period depending on the clinical situation and whether an obstetrician or GP refers the patient.

  • THIRD TRIMESTER ULTRASOUND

    During the third trimester, an ultrasound can check the fetal position, placental appearance and site, how much fluid is around the baby, fetal well-being and the baby’s growth compared with previous scans and the expected date of delivery.

    Whether Medicare will provide a rebate for one or more scans during this period, depends on meeting certain clinical criteria and whether an obstetrician or GP refers the patient.

  • AFTER ULTRASOUND

    One of our radiologists will interpret the scan and provide your referring doctor with a comprehensive report about the findings. The results of your scan will be sent directly to your referring doctor, and it is very important you book a timely follow-up appointment to discuss your results.

  • 3D/4D PREGNANCY ULTRASOUND

    ln addition to our diagnostic obstetric ultrasound service, we also offer elective 3D/4D Ultrasound.

    3D Ultrasound gives us the ability to see the surface of your baby to look at beautiful facial features, fingers and toes. 4D simply means watching your baby’s expressions and movements as they happen in real-time. The best time for this scan is between 26 and 30 weeks when your baby has sufficient fat under their skin and is still relatively high in the uterus. A 4D scan is not a medically indicated scan and therefore attracts no Medicare rebate, and will require an additional referral from your doctor.

  • PATIENT SAFETY

    Ultrasound is a safe examination which provides excellent imaging without any known risks. Our staff use ultrasound with care to ensure that patients benefit from what ultrasound offers, with minimum risk. At South Coast Radiology we employ experienced, qualified sonographers accredited with the Australian Sonographer Accreditation Registry, and invest in the latest equipment to ensure patients receive the very best patient care.
