Chest CT Scan Perth
Most chest CT scans at ChestRad require no injections or other medications, though some, such as scans to rule out pulmonary embolus or for diagnosing or monitoring cancer, will.
At ChestRad, we use advanced technology to ensure that most of our Chest CT Scans are performed with ultra-low radiation doses, prioritising safety and accuracy. Generally, no special preparation is needed beyond fasting for two hours prior to your appointment. The procedure involves you lying on your back, though some cases may require you to lie on your stomach. The entire procedure is quick, with only a few minutes spent on the table. Typically, you’ll be asked to take a deep breath in for the first scan and then exhale fully for a second scan, which is done with a minimal radiation dose—even less than a standard chest X-ray. This second scan helps assess any potential airway issues affecting ventilation.
What is a Chest CT Scan?
A Chest CT (Computed Tomography) scan is a non-invasive imaging technique that provides detailed cross-sectional images of the chest area, including the lungs, heart, blood vessels, airways, and other structures. Using advanced X-ray technology, a chest CT scan captures high-resolution images that offer more detail than standard X-rays, helping physicians detect and diagnose a variety of chest-related health issues. This type of scan is quick, usually taking only a few minutes, and is performed with the patient lying comfortably on a scanning bed that moves through a donut-shaped CT scanner.
Why You May Need a Chest CT Scan
It is often recommended to investigate symptoms like persistent cough, shortness of breath, chest pain, or unexplained weight loss. CT scans are also critical tools for diagnosing conditions such as infections, lung cancer, blood clots (pulmonary embolisms), and heart disease. If you’ve had abnormal findings on an X-ray or have risk factors for certain lung conditions, a chest CT scan provides a more detailed look, allowing your healthcare provider to make accurate diagnoses and develop effective treatment plans tailored to your needs.
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.
