MRI Obstetric (Fetal & Maternal) Scans Sydney
MRI Obstetric is a specialised, radiation-free scan used to assess the developing fetus and maternal structures when ultrasound alone does not provide enough information. It is safe during pregnancy and offers high‑resolution detail for complex or unclear findings. Medicare-eligible obstetric MRI studies are fully bulk-billed at Advicon Imaging.

Description of MRI Obstetric (Fetal & Maternal)
Obstetric MRI uses powerful magnetic fields—not radiation—to produce detailed images of the fetus, placenta, uterus, and maternal anatomy. It is typically performed in the mid to late stages of pregnancy when additional clarity is needed beyond ultrasound.
MRI Obstetric may be requested for:
- Fetal structural abnormalities
- Brain development concerns
- Lung or thoracic abnormalities
- Abdominal or gastrointestinal issues
- Spine and neural tube assessment
- Placental abnormalities (e.g., placenta accreta spectrum)
- Uterine or maternal pelvic concerns
- Twin complications (e.g., TTTS follow-up)
- Clarification of equivocal ultrasound findings
MRI is particularly useful for evaluating fetal brain development, congenital abnormalities, and subtle soft tissue structures that ultrasound cannot fully visualise due to fetal position, maternal body habitus, or low amniotic fluid.
MRI Safety:
MRI does not use ionising radiation and is considered safe during pregnancy. At Advicon Imaging, obstetric MRI is performed with protocols specifically designed for pregnant patients.
Additional Notes:
- Obstetric MRI is usually performed from mid‑pregnancy onward.
- Please bring all prior ultrasounds to assist our radiologists.
- We prioritise comfort and safety throughout the scan.

Frequently Asked Questions
Is MRI safe during pregnancy?
Yes. MRI uses magnetic fields instead of radiation and is widely considered safe during pregnancy. We use pregnancy‑specific protocols.
Why do I need an obstetric MRI?
Your doctor or specialist may need clearer information about fetal development, the placenta, or maternal anatomy when ultrasound alone is insufficient.
Do I need preparation?
No special preparation.
- Continue normal eating and drinking
- Wear comfortable clothing
- Remove metal items
- Bring previous ultrasound reports
Will contrast be used?
No. Gadolinium contrast is not used during pregnancy.
How long does the scan take?
Usually 25–40 minutes depending on the complexity of the study.
Will I need to lie on my back?
We position pregnant patients safely and comfortably, often slightly tilted to avoid pressure on major vessels.
Will the baby be harmed by the scan?
No. MRI is safe for both mother and fetus. There is no radiation.
Can I hear or feel anything unusual?
The scanner makes tapping sounds—ear protection is provided. Some mothers feel fetal movement during the scan.
When will the results be available?
Reports are generally sent to your referring doctor or obstetrician within 24–48 hours.
Is the scan bulk-billed?
Yes. Medicare-eligible obstetric MRI referrals are fully bulk-billed at Advicon Imaging.
