Preparation
What to do before your scan.
Most scans need very little preparation — but a small amount of planning makes the day run smoothly. Find your modality below.
CT scan (with IV contrast)
- Fast for 4 hours before the scan — water is fine.
- Continue your regular medication unless your doctor says otherwise.
- Wear comfortable clothes without metal zips or studs in the area being scanned.
- Mention any history of kidney disease, diabetes or contrast allergy when you book.
CT scan (without contrast)
- No fasting required.
- Bring your referral, Medicare card, and any prior imaging.
- Wear something comfortable with no metal in the scan area.
CT Calcium Score
- No fasting required.
- Avoid caffeine and intense exercise for 24 hours before the scan — it raises your heart rate.
- Wear a metal-free top across the chest area.
Abdominal ultrasound
- Fast for 6 hours — no food, no water.
- Don't smoke in the 6 hours before the scan.
- If you MUST take medications please take them with as little water as possible.
Pelvic ultrasound
- Drink 1L of water in the hour before your appointment.
- Don't empty your bladder — a full bladder gives the clearest images.
Pregnancy ultrasound
- For dating scans (under 13 weeks): arrive with a moderately full bladder.
- For mid-pregnancy and growth scans: no special preparation.
- You can bring one extra person in the room, and an interpreter as well.
X-ray
- All X-rays are walk-in during clinic hours.
- Bring your referral and Medicare card.
- Wear clothing free of metal in the area being imaged where possible.
- Let us know if there's any chance you could be pregnant.
Dental imaging (OPG, Lateral Ceph)
- Remove glasses, earrings, hairpins and necklaces before the scan.
- Bring your referral (a photo on your phone is fine).
- The scan itself takes 15–30 seconds depending on the study.
Image-guided injections
- Continue your normal medication unless we or your doctor has advised otherwise.
- Bring any prior imaging or reports your doctor referenced in the referral.
- Arrange for a driver if possible.
- Allow up to 45 minutes at the clinic.
3D / 4D baby scan
- We only scan from 26–32 weeks.
- Drink plenty of water the day before so you're well hydrated.
- A small snack about an hour beforehand makes most babies more active.
