Northern Ultrasound for Women

COVID-19 Ultrasound Protocol

We are operating as normal but are taking all appropriate precautions and complying with Government COVIDSafe regulations to ensure a safe and healthy environment for patients and staff.

We are screening every patient prior to attending their appointment. Our rooms are sanitised daily with extra cleaning of high touch-point areas. Hand sanitizer and sanitized pens are provided for each patient.

Air purification systems with internal UV-C have been installed in the waiting and ultrasound rooms.

Social distancing is in effect, temperatures are checked on arrival and the wearing of face masks is mandatory by patients and accompanying person while in the waiting room and during appointment.

We have implemented the following protocols:

    • Requesting patients with pre-booked appointments to call ahead of the appointment if experiencing any of the COVID-19 symptoms - fever (+ 37.5 deg. C), cough or shortness of breath, sore throat, aches and pains, loss of taste or smell (see or have been in contact with another person with known or suspected of COVID-19 in the last 14 days.
    • Requesting patients to attend the appointment alone or strictly one support person (adult) to attend and for the support person to be free of all COVID-19 symptoms and comply with all screening criteria.
    • Strictly no children under age 16 to attend the appointment.
    • Requesting patients and any support person to wear a face mask, disposable masks will be provided if necessary but it is advised to bring your own face mask.
    • Ensure you have responded to your SMS appointment confirmation as evidence of your appointment, if asked to show evidence by authorities.
    • Support person will be required to provide contact details using our QR Code, to comply with DHHS regulations for the purpose of contact tracing
    • On the day of your appointment, you may be asked to wait outside the waiting room for a short period to comply with social distancing rules.

Our reception staff will be asking screening questions ahead of appointments. We’re confident that patients will understand why they are asked to wear a mask or asked to defer appointments if they are experiencing any COVID-19 symptoms.

Our Doctors and Sonographers will be wearing P2/N95 masks as protective equipment.

Northern Ultrasound for Women is not equipped to cater for infection isolation, therefore if you are concerned you may have been exposed to COVID-19, you should contact your GP, referring doctor or the emergency department immediately.

Our priority is keeping our patients and staff members safe whilst maintaining the highest standards of ultrasound imaging and service. If you have any queries please do not hesitate to contact our helpful staff on 9457-1466.

Referral Timing Guide

Gynaecological Scan Timing Guide: Indication & Suggested Timing

Abnormal uterine bleeding

  • Preferably in the early proliferative phase i.e. days 4 – 10 of the cycle (the endometrium is thinnest and more easily assessed at this time)

  • For women with irregular bleeding anytime apart from their heaviest days of bleeding (to avoid obscuring views of the uterine cavity)

Postmenopausal Bleeding

  • Anytime if not on HRT

  • Temporary withdrawal of HRT at least 10 days prior to the scan minimizes any exogenous effects on the endometrial lining


  • Day 21 is best for determining if ovulation has occurred in that cycle

Follow up of Ovarian Cyst(s)

  • The early proliferative phase of the cycle is best for avoiding confusion of a previous cyst with an active corpus luteum in the present cycle

Pelvic pain

  • As indicated by clinical symptoms

Obstetric Scan Timing Guide:Indication & Suggested Timing

Early Pregnancy for dates and life

  • Embryonic heart may be detected from as early as the sixth week however establishing embryonic life may not be possible until the seventh week

Suspected ectopic pregnancy

  • Anytime once there is a positive B-hCG. Menstrual data is unreliable in diagnosing ectopic pregnancies and a quantitative B-hCG level is extremely useful as a diagnostic criteria (the absence of an intrauterine gestation sac once this level has reached 1000iu/l is highly suspicious for an ectopic unless proven otherwise).

First trimester screening for Down syndrome

  • The ultrasound scan for the nuchal translucency risk assessment is done in the 11 – 14 week window. Risk assessment may not be possible outside of this time frame depending on the fetal length (CRL).

  • For the Combined First Trimester screening programme the maternal serum can be drawn between 10 – 13 weeks. It is strongly recommended that the maternal serum be obtained at least one week prior to the scan to expedite the combined risk results from the central VCGS laboratory once the ultrasound data is sent in.

Chorionic Villus Sampling

  • From 11 – 14 weeks. Full results will take up to two weeks.

Mid trimester anatomical survey

  • The optimal window for the fetal anatomical survey is 18 – 20 weeks


  • May be scheduled electively from 15 weeks gestation onwards

  • For diagnostic testing of abnormal mid-trimester findings, an urgent counseling and amniocentesis may be requested with rapid analysis (FISH) results available in 24 – 36 hours. Full results will take up to two weeks.

Tubal Patency Studies

  • Scheduled during days 4 - 10 of the regular menstrual cycle.
