Computed tomography (CT) combines a rotating X-ray beam with computer processing to create detailed cross-sectional pictures — thin “slices” of the body that show bone, soft tissue and blood vessels far more clearly than a plain X-ray.
Our scanner uses dose-reduction technology, and every study is tailored and reported by our on-site Radiologist. Some scans use an iodine-based contrast injection to highlight blood vessels and organs.
What to expect
- You lie on a padded table that moves smoothly through a short, open ring — it is not a tunnel.
- If contrast is needed, a small cannula is placed in your arm; the injection can cause a brief warm flush and a metallic taste, which passes quickly.
- You may be asked to hold your breath for a few seconds while images are taken.
- The scan itself usually takes less than ten minutes.
Types we offer
- Brain & sinuses — headache work-up, sinus disease and more.
- Spine & musculoskeletal — neck, back, and detailed bone imaging.
- Chest — lungs and chest, including low-dose techniques.
- Abdomen & pelvis — organs, unexplained pain and follow-up.
- CT angiography — blood vessels, with contrast.
- CT-guided injections — precisely targeted spinal and joint injections.
How to prepare
| Examination | Typical preparation |
|---|---|
| Scans without contrast (most brain, sinus, spine, bone) | Usually no preparation — arrive as you are. |
| Scans with IV contrast | Do not eat for 2–4 hours beforehand; water and usual medications are fine. A recent kidney-function blood test may be requested. |
| If you have diabetes or kidney problems | Tell us before your scan — some medications need adjusting around contrast. |
| Some abdominal scans | You may be given a drink of oral contrast about an hour before. |
These are general guidelines — please follow the specific instructions we give you when you book or arrive.
What to bring
- Your referral and your Medicare, concession or DVA card.
- A list of your medications, and any recent kidney blood-test results.
- Previous imaging of the same area, if you have it.
Your results
Our on-site Radiologist reviews your images and sends a formal report to your referring doctor, who will discuss the results with you. Urgent findings are communicated to your doctor promptly.
Common questions
How much radiation will I receive?
More than a plain X-ray, but modern dose-reduction keeps it as low as practical, and your doctor has weighed this against the benefit of an accurate diagnosis. Tell us if you have had recent CT scans elsewhere.
Is the contrast injection safe?
Iodinated contrast is very safe for most people. Mild reactions are uncommon and serious ones are rare; our team is trained and equipped to manage them. Tell us about any previous contrast reaction, asthma, allergies or kidney problems.
I am claustrophobic — will I cope?
Almost always. A CT scanner is a short open ring rather than a tunnel, and the scan is over in minutes.
What if I am pregnant?
Tell our staff before the scan. CT is generally avoided in pregnancy unless the benefit clearly outweighs the risk — we will discuss alternatives with your doctor.
