CT Venogram Scans Sydney
A CT Venogram is a specialised CT scan that uses contrast dye to create detailed images of your veins. It is commonly used to detect blood clots, venous blockages, and abnormalities in the brain, abdomen, pelvis, or limbs. At Advicon Imaging, Medicare-eligible CT Venograms are fully bulk-billed.

Description of CT Venogram
A CT Venogram (CTV) is a fast, non-invasive imaging test designed to assess the veins and identify conditions such as thrombosis (blood clots), venous obstruction, or abnormal vascular anatomy. It is especially useful in diagnosing cerebral venous thrombosis, deep venous thrombosis, pelvic vein congestion, and for mapping venous pathways prior to surgical or interventional procedures.
During the scan, an iodine-based contrast agent is injected through a vein in your arm. This highlights your venous system on the CT images, allowing radiologists to clearly visualise blood flow, blockages, collateral circulation, or anatomical variations. The scan provides wide anatomical coverage and can be combined with arterial-phase imaging if both arteries and veins need assessment.
CT Venography is highly accurate, fast, and a preferred alternative when ultrasound is inconclusive or when deeper veins require assessment. It is also an important tool for preoperative planning, as it helps surgeons understand venous structure and potential risks before intervention.
At Advicon Imaging, we use low-dose CT technology and modern protocols to produce high-quality venous imaging while minimising radiation exposure. All Medicare-eligible CT Venograms performed with a valid referral are bulk-billed.
Frequently Asked Questions
What is a CT Venogram?
It is a CT scan that uses injected contrast dye to create detailed images of your veins and detect blockages or clots.
Why has my doctor ordered this test?
Typical reasons include suspected blood clots, venous obstruction, pelvic congestion, abnormal swelling, headaches related to venous issues, or pre-surgical vein assessment.
Do I need preparation?
Preparation may vary depending on the area being scanned.
- Avoid eating for several hours if contrast will be used.
- Remove jewellery or metal objects from the scan region.
- Inform us if you have kidney disease, diabetes, asthma, thyroid problems, or prior contrast reactions.
- Women should notify us if pregnant.
What happens during the scan?
A contrast injection is given through an IV in your arm. You will lie on a CT table while images are taken. The scan itself is quick, usually only a few minutes.
Is the scan painful?
No. The scan is painless. You may feel a warm sensation or metallic taste during contrast injection—this is normal.
Is contrast safe?
Most people tolerate it very well. Rare allergic reactions can occur. Please notify staff of any previous contrast issues.
Does the scan involve radiation?
Yes, the scan uses X-rays, but the dose is minimised using modern CT technology.
How long does the scan take?
The scan itself takes 5–10 minutes. If contrast is used, your total visit may be around 20–30 minutes.
Can I drive afterward?
Yes. You can resume normal activities unless advised otherwise.
When will my doctor receive the results?
Reports are usually available within 24–48 hours, or sooner for urgent cases.
Is this scan bulk-billed?
Yes. Medicare-eligible CT Venograms are fully bulk-billed at Advicon Imaging.
