Chest CT Scan Perth


Our chest CTs are exceptionally high quality and genuinely low radiation dose, with sub-millisievert scans for all lung cancer screening patients (reference: American Association of Physicists in Medicine Lung Cancer Screening Protocols under Siemens Drive and Naeotom Alpha machines).

Most Chest CT scans at ChestRad are performed using ultra-low dose techniques, prioritising patient safety without compromising image clarity. In most cases, no preparation is required beyond fasting for two hours before the procedure. You’ll typically lie on your back (or occasionally your stomach), and the scan itself takes just a few minutes. During the scan, you may be asked to take a deep breath in and out to assess lung ventilation. Our protocols ensure that even the second scan is performed with a dose lower than a standard chest X-ray.

What is a Chest CT Scan?

A chest CT (Computed Tomography) scan is a non-invasive imaging test that creates high-resolution cross-sectional images of your chest, including the lungs, airways, heart, and blood vessels. Using advanced X-ray technology, it provides far more detail than a regular X-ray. At our Perth clinic, chest CT scans are quick and painless, typically completed in just a few minutes as you lie on a motorised table passing through the scanner.

Why You May Need a Chest CT Scan

A CT scan of the chest may be recommended if you’re experiencing symptoms such as persistent coughing, chest pain, shortness of breath, or unexplained weight loss. It’s also valuable in diagnosing conditions like lung infections, blood clots (pulmonary embolism), heart disease, or lung cancer. If previous imaging, such as a chest X-ray, reveals abnormalities, a CT scan provides a more precise and more detailed view to guide accurate diagnosis and treatment planning.

Frequently Asked Questions

How is a Chest CT scan different from a regular X-ray?
A chest CT scan provides much more detailed, cross-sectional images than a standard chest X-ray, making it more effective for detecting small or complex issues in the chest area.

Do I need to prepare for a Chest CT scan?
Generally, no extensive preparation is required, although fasting for about two hours before your appointment may be necessary.

Will I be exposed to a lot of radiation?
Chest CT scans at many clinics use ultra-low radiation doses due to advanced technology, so you will receive minimal exposure while still getting accurate images.

How long does the scan take?
The scan itself is quick, often only taking a few minutes. Most of the time is spent positioning you on the table and ensuring your comfort.

Will I need contrast dye for my scan?
Some scans may require a contrast dye to improve the visibility of certain structures. Your doctor will inform you if this is necessary, and you will be asked about any allergies or medical conditions beforehand.

What should I expect during the scan?
You’ll lie on a table that slides into the CT machine, which may feel like a large doughnut around you. You might be asked to hold your breath for short periods to capture clear images, but the scan itself is painless.

Is the procedure safe?
Yes, Chest CT Scans are considered safe, especially with modern, low-dose equipment. However, as with any imaging involving radiation, it’s used judiciously to ensure patient safety.

Can I resume my normal activities after the scan?
Yes, there’s no recovery time needed, so you can resume your usual activities right after the chest CT scan.

How soon will I get the results?
Results are usually available within a few days, though urgent cases may be reviewed sooner. Your doctor will discuss the findings of your CT scan with you and any next steps.
